- What's she says: I'm fine
- What she means: can you imagine how terrible it was for ned stark to listen to his best friend go on and on for decades about murdering every last targaryen on earth because of what (robert thinks) happened to lyanna, while knowing all he has left of her, the last connection he has to his beloved sister, is in fact a targaryen? and then how hard it must have been for him to make his wife believe he was unfaithful to her, when really he was just being truly honorable™ ned stark and protecting his dying sister's wish? then he had to painfully watch as his wife not-so-subtly treated his 'bastard' like the kid was significantly lesser than his other children? and THEN had to sit back while the kid basically agonizes over his mother and feed him lies his whole life? imagine being the only one with that kind of secret.
The big problem I have with Tokka is that I really can't see Sokka being unfaithful, it goes against all of his A:TLA character development. And it can be argued that his relationship with Sukki was one of the strongest and most developed in the series.
