1. He has the potential to be a True Alpha. However, that requires having more control, fixing his anger issues, experience, and getting past other issues.. and he's obviously quite far from being at that point. Almost like Smallville!Clark, who had to go through a lot of trials and accept destiny (and 10 seasons) to become who he was meant to be. It also may depend on if things between himself and Scott are good, due to the bond of alpha and beta being akin to brothers, or parent and child (which Gerard even hinted at).
2. He actually WAS Clark Kent before; when he was a younger kid, he played him in a school play, sort of a mock adaptation thing for the Man of Steel movie. Coincidentally, he happens to look just like the movie actor that played the superhero in flashback scenes.
3. He's bi, but it never came up since he's not really into putting labels on things. He hasn't slept with Mason ever either since they're best friends, and felt doing that would just make their friendship dynamic way more complicated than it had to be. He had been with a few guys before in his previous school, it's just never brought up since it's not a big deal.
4. Unknown on the show, but this Liam wants to be a really good doctor one day. Or at least to be able to have a profession that involves either healing or protecting others, and being a doctor seems the best way. Also being a werewolf (and knowing some Druid herb remedies) also adds more perspective for him in that area as well.
5. After the recent events at the Hill Valley Zoo, he may be more open to accepting Theo as an ally, than before. Or perhaps more than just an ally? Possible. He still hates what the other wolf had done in the past, killing, and other things.. but then again, since his resurrection, Theo has also saved Liam at multiple times against deadly odds. Also, having stopped Liam from killing Nolan by knocking Liam out-- and actually let the little human go, when Theo would have been into pro-murdering him in past seasons. Fighting each other at the zoo also seemed to help him get through a few anger issues too. If asked how he can dislike someone, and also be accepting of them, he'd just say "it's complicated." Mostly because he himself doesn't even know.
