^ except that the cleansing of saiden happened in Winter's heart;)
For me, in Fires of Heaven (I think?) when Rand is bringing the Aiel back across the dragonwall afte rthe Shaido, and they're just about to begin that big battle in Carhien, and as it's happening Mat's trying to run away from it all and blunders into that carhienen/tairen column of soldiers about to walk into an ambush, fights himself over it and finally decides to warn them, promising himself he'll leave right after, and ends up leading the entire thing throughout the whole battle. Afterwards it mentiones that mat kept trying to sneak away form them again and after time followed after him and ended up blundering into some great big battle that he had to save them from again. just picturing that whole thing in my mind, I thought it was pretty hilarious, and it's also the first time we see Mat using his new tactical knowledge. Pretty much everything with the Band of the red hand afterwards I thought was great, including the new stuff in Knife of Dreams when he's finally reunited with them.
