What would've happened if Theon actually had the chance to go join the Night's Watch at the end of "A Clash Of Kings"?
so jon wouldn't have been there when he reaches it, and i think he'd be bitchy and whiny and trying to curry favour and take control to make up for his wounded pride at winterfell. i feel like he could fall in with alliser thorne and janos slynt, or make his own ragtag crew of rapists and murderers that he thinks are funny and goes to mole town and does not respect his vows and sexually harasses satin. by the time jon snow arrives back, i think a) jon immediately kills him after learning about all that happened and gets in major trouble b) jon is so disgusted by theon he defects BACK to the wildlings (crazy lol) c) jon understands that the wildling threat is too important and that he will deal with theon later, like he could use his skills as a bowman in the battle.
after the battle and stannis taking control, i think stannis could use the punishment of theon as leverage to garner jon's support, the same way he does with winterfell and legtimisation and lordship. and i think jon being given the option for revenge would sway him more than the option for winterfell, but he'd still say no.
theon would fall in with alliser thorne and janos slynt i think, mostly cos the other factions would dislike him. i don't think he'd like bowen marsh, i think he'd want to get in with denys mallister but denys mallister is too ironbornphobic (justified in theon's case LMFAO) to accept him, and cotter pyke is 50/50 i think he could have a ironborn to ironborn connection with theon but idk i think he'd HATE theon for being a pompous little lordling who is ironborn only in name. so its janos slynt for theon. once jon becomes lord commander, i think he's either keeping theon where he can see him (friends close enemies closer, which lord commander snow fucking LOVED doing lol) or might send him away to eastwatch just so he doesnt have to see him anymore. and if he gets sent to eastwatch, ramsay intercepts the caravan and steals theon away LOL. destiny will come for theon!
but if theon stays at winterfell, maybe he can prove himself to jon somehow. maybe after seeing jon behead janos slynt he gets the kick in the nuts he needed. maybe he begs leave of jon to find bran and rickon and prove that they are alive, maybe he gets the secret out of sam somehow in his desperation to prove himself innocent (still killed those kids tho). and then you can have him going up north to bloodraven (maybe bloodraven sends him some visions... maybe theyre euron related.....) or going off to rickon and somehow meeting up with davos and wyman and wyman is fully trying to kill him. assuming the boltons still take control of the north.
and maybe theon and jon can frot a bit idk
