I don't think the Roxy thing is a mislead. It would be one thing if all we got was uu's speculation, but we were flat-out shown what was going on with her. Homestuck isn't one to have an "unreliable narrator" when we're explicitly shown what's going on. The narrator can be unreliable, but AFAIK, only by omission.
I mean, consider Dirk's situation. The viewpoint blacked out before both his dreamself and realself fell asleep, but no one's doubting that.
