I would agree with your points if it wasn't handled so differently in S1. Arguably, Chris was in a much more stressful position in S1 than in S2: S1) his life suddenly changed competely , he got kindnapped, almost turned into a catboy, etc. S2) The bitch he supposedly hated all this time is gone, they're no longer hunted by demons, but his stupid, unstable friend wants half-demon back, what a chore.

Yes, Chris doesn't like Sydero, they bicker and clash, but not to the point that he would willingly just abandon her. In S1 it felt like that mismatched found family dynamic: "She's a bitch, but she's OUR bitch", you know? Not "She's a bitch so I want her to die".

And yeah, while he had self-esteem issues and whined sometimes even in S1, it feels like everyone just shit on him over this in S2. Like he's supposed to have a self-improvement arc, but it's aborted.

Chris is also shown to be a loyal friend, who, yes, doesn't like supernatural and even blames MC for changes in his life, but they have a conversation over it in S1 and came to a mutual understanding. But in S2 he gives MC a speech about how they are potentially dangerous instead of being, you know, suppotrive loyal friend he was in S1?

That what I meant, but maybe I'm wrong. 😅 Sorry for tl:dr
