Hi, everyone, I'm re-watching the show for the second time but I'm kinda confused about the timeline. Does anyone knows how old is Ian in Season 5? I think he might be 19, because Lip is 22 and he's 3 years older than Ian, but when I do the math I see that he'd be 20. But it just doesn't make sense to me? So, I'd really appreciate it if someone could just please clear it up for me. Thanks!
