Yeah, no doubt. The High Sparrow must have known that Tommen would tell Cercei anything he said, given how easy Tommen is to manipulate, so I'd say the High Sparrow is using the Lannisters, who in turn are trying to use the Tyrell's.
 
Fuck knows what he said though. Probably something to incite anger and violence in an attempt to overthrow the state.

I'm guessing he told Tommen that it was the Tyrell's that had a hand in killing Joffrey. 
Namely Grandma Tyrell ( Queen of Thorns)

Yep, and Cersei is playing both sides to set the Tyrells up for a fall while they are wiping out the Sparrow.

Some nerd picked up that during the scene where Cersie agrees to work with the Tyrell's the music in the back ground was 'the rains of Castamere' 
We all know that went the last time it was played...

Okay since we aren't doing spoilers now, as I put in my spoiler earlier... 
 
I absolutely think that the incest twins are going to use this to try to destroy the Tyrell's.
 
My guess, and this was made whilst watching the show as I turned to my better half and told her this... is that what the Sparrow told Tommen was information gained from torturing Loras - which was that Lady Olena was responsible (along with Little Finger) for the poisoning death of Jofferey.
 
This would explain why the incest twins looked so determined - determined for revenge rather than protecting the Queen (Margerey Tyrell)!
 
So I think that the Lannisters are using the mis-information that Margerey will be made to do the walk of shame to draw the Tyrell army into the city because as we know, a large army like that is much less effective in the house to house fighting as it is on a field of battle.
 
The one weakness to this theory is just how (and using what army) will Cersie and Jamie to do this given they only have the City guard at their disposal (that I know of). Perhaps the Lannister forces will be laying in wait for Tyrells to show up?

I'm not as big a GoT nerd so had to look it up. Apart from the Red Wedding it has featured strongly at times including Cersei explaining it to 'scare' Margery.

And it appears this theory is pretty much the stock theory around the interweb.
 
From the Time website (<a data-ipb='nomediaparse' href='http://time.com/4337568/game-of-thrones-theory-high-sparrow-tommen-secret/'>http://time.com/4337568/game-of-thrones-theory-high-sparrow-tommen-secret/</a>) 
 
Warning: This post contains spoilers from the sixth season of <a data-ipb='nomediaparse' href='http://time.com/4328562/game-of-thrones-ramsay-bolton-umbers-conspiracy-theory/'>Game of Thrones</a>.
After a conversation between <a data-ipb='nomediaparse' href='http://time.com/4336622/game-of-thrones-women-sansa-cersei-yara-daenerys/'>Cersei</a> and Tommen in the <a data-ipb='nomediaparse' href='http://time.com/4336953/game-of-thrones-daenerys-targaryen-fire-immunity/'>fourth episode</a> ofGame of Thronesâ€˜ sixth season ended with the young king preparing to reveal a mysterious secret to his mother, viewers were left wondering what he had been hiding. The information in question had been told to him in confidence by the High Sparrow â€” presumably during the pairâ€™s exchange last week â€” and seemed to be gravely upsetting for the boy. â€œMother, thereâ€™s something I want to tell you, something the High Sparrow told me,â€ he says nervously. â€œI promised him I wouldnâ€™t tell anyone.â€
The scene cuts off shortly afterwards, segueing into a sequence in which Cersei and Jaime burst into a meeting between Olenna Tyrell and current Hand of the King Kevan Lannister to broker a deal with them. The agreement involves the Tyrells bringing their army to Kingâ€™s Landing in order to take down the Faith Militant and prevent the High Sparrow from forcing Margaery to make the same walk of atonement that Cersei was subjected to in the season five finale â€” a plan that Reddit user WriteOnSC thinks might reveal more about Tommenâ€™s confession.
<div style="color:rgb(40,40,40);font-family:Georgia, serif;font-size:19.2px;">â€œItâ€™s my belief that the High Sparrow told Tommen about the Tyrellsâ€™ involvement in Joffreyâ€™s murder,â€ <a data-ipb='nomediaparse' href='https://www.reddit.com/r/gameofthrones/comments/4jjqi9/everything_my_theory_about_what_the_high_sparrow/'>the Redditor writes</a>. â€œJudging by the tears in his eyes when heâ€™s about to tell Cersei, it seemed to be the worst possible news. I believe itâ€™s Ser Loras who revealed this information as he seemed absolutely broken by his solitary confinement. Immediately after Tommen tells her the news, Cersei and Jaime show up to the small council with a plan to invite the Tyrell army into Kingâ€™s Landing to deal with the Seven and protect Margaery from a [walk] of atonement. I believe this is a ruse by Cersei to draw the Tyrells into her scheme. The Tyrells picking a fight with the Seven will create unrest among its followers/citizens of Kingâ€™s Landing. They will turn on and blame the Tyrells with the Lannisters â€˜standing down.â€™ This creates a war between two of Cerseiâ€™s least favorite factions: the citizens of Kingâ€™s Landing who treated her like garbage during her walk of atonement, and the family responsible for her sonâ€™s murder. Every dead body is a win.â€</div>

Sure, but like most things in GoT and A song of Ice and Fire, things most often don't turn out as expected.
 
In fact, a "war" between Lannister and Tyrell may just put the "Sparrow" and his followers in a stronger position as the two main forces in and around Kings Landing destroy or severly weaken each other.
 
One thing would really piss me off is if Lady Olenna falls for this as she has come across all series (and in the books) as a very shrewed player of the "game of thrones". Surely she should be able to see through this possible plot of the incest twins.
 
In fact, there is considerable chat on the interweb as to whether or not Ser Loras would have even known of the successful plot to poison Jofferey as Margerey only found out after the peice and that was only to insure she went into marriage with Tommen fully informed. Olenna would have had no reason to tell Loras who has already showen he is happy to give away Tyrell secrets in pillow talk with his various lovers.

Don't think it's been mentioned but did anyone else enjoy seeing Ser Alliser get hanged ?
 
What an arsehole that guy was.

Hmmm. While I'm sure the High Sparrow is happy to see the Lanisters and the Tyrells kill each other, I don't think he'd be too keen on facing the 2nd strongest army in Westeros led by arguably the best commander,i.e Fat Sam's dad. 
I also don't believe Loras or his sister knew about Joffrey. They didn't need to know and probably would have screwed things up if they had. 
But what else could the HS have told Tommen? He wouldn't have believed the incest thing. 
It should also be remembered that Cersei is facing a trial by combat soon and would be keen to avoid it. 
But I assume that fight will take place and it will be between dead Gregor and not dead and now very holy Sandor (burnt face dude). 
It's all very exciting even though it's infuriating how they're pissing more and more on the books. Ultimately the fat, old perve has himself to blame for not getting on with it.

Maybe the High Sparrow is playing Tommen knowing he will tell Cersei any lie he tells him...although surely as a man of God he wouldnt sin and lie to Tommen.

Judging by the state of him you'd assume his fighting days were over. But then again his big older bro ( played by an actor 20 or so years younger ) made a hell of a recovery.

Yeah I reckon it's inevitable. In the books at least someone resembling him had joined the faith.
 
Having him fight his psycho undead brother is just too cool to not have in the show.
 
Didn't Ayra also forgive him in an earlier episode? He's one of the good guys now.
 
So, a wild, probably bullshit prediction is that the Tyrell's pull a fast one on the Lanisters (possibly by confessing the plot to the HS) and the trial goes ahead. Cercei thinks, no big deal I have the monster. Faith then reveals Sandor. Sandor wins. Cersei farked. But then Dani shows up.
 
I wonder if you can bet on who tops LF in the end. I'm thinking that Robin gets buttered up by Sansa and orders him through the moon door. Either that or Ayra kills him. But I think she'll take out Cersei.
