I haven't read the whole thread (I mean the comments) so sorry if this has been addressed already.
I think by not telling that Jeyne is not really Arya, Theon keeps on damaging House Stark. I don't have it in my heart to blame Jeyne because she was an innocent when she went through Ramsay's abuse (Theon wasn't) but I still think she should tell the truth. That whole comment about "she'll be a little more than a whore" is exaggaration. While she may not exactly be very highborn and noble, House Poole still served the Stark's honourably, and I don't think Stannis would just see an abused girl as a whore and give her to his men or something!
So Theon took Winterfell behind Robb's back, killed two innocent children and their parents to cover up his own stupidity, unknowingly unleashed Ramsay the Supreme Psychopath of the North, cast the first stone of Robb's gruesome death ("The Stark cause was finished the moment you took Winterfell" - Roose), let his men rape and burn and he even raped Kyra himself... And NOW he is convincing everyone that some "steward's whelp" is Arya Stark, who may very well be pregnant with Ramsay's son who WOULD inherit Winterfell after him, if Theon has his way.
I'm sorry but what "redemption" are you people talking about? I don't think child murderers and rapists get redemption.
Let someone just sacrifice him and be done with it. (Preferably to R'hllor because it would hurt more, but I'll accept the Old Gods as well.)
Here here. Throw a scumbag some sufferring fron his/her own pov and everyone loves you and wants you to be the new king (kingsmoot x2 lovers).
