I know we always joke about Puck’s whole pool cleaning business all the time, but…
You know, I may have some thought for you on this one, and it deals with all the instances you brought up. Yes, they didn’t show any of those things bothering him, and my guess is (and yes, this is only a guess, but just go with me on this for a moment, please) is that he isn’t showing that it bothers him. Or he has been pushed down so many times and hid it bothering him for so long, that he has convinced himself that it doesn’t bother him anymore.
Let me explain:
- He tries to be responsible for Beth when he finds out Quinn is pregnant and she calls him a Lima Loser and tells him that there would be no way she would admit that it was his (I’m not hating on Quinn, exactly. She was dealing with her own things. I’m just stating what happened). She only fesses up when someone else lets it slip that he is the father. He admits that he cared about her, and the next year, she acts like he doesn’t even exist.
- His whole relationship with Rachel. Whether you ship Puckleberry or not, they did show that there was a friendship there at some point, yet it sadly seems that Rachel seems to use that friendship for her own gain, regardless of how it makes him feel. (This is hard for me to write, because I happen to ship Puckleberry, but once or twice, this has happened, whether I like it or not. Using him to get back at Finn is one of the instances.). I still think (although it might just be headcanon at this point) that she cares about him as a friend, but she really doesn’t show it much anymore, which is sad.
- He works to date a girl, falls for her, (Lauren) and she breaks up with him because it brings down her reputation.
- He “falls” in love with someone else (I still think the whole “Shuck” relationship was ridiculous), and what does she do? Yup, that’s right, use him just like everyone else does.
He keeps constantly having people use him in one form or another. Did you see anyone try to tell him that he wouldn’t be dead or in jail in 20 years? No. Sure, the writers tried to use that as a joke, but it really isn’t. It’s a cry for help from a boy who really thinks that he isn’t good for anything except for being used by everyone he knows, because that’s all he’s ever been shown.
So that’s my long explanation. I don’t know if it makes sense to anyone else or not.
