The Ridge guitar intro transcription

So far, Spotify hasn’t been very useful for discovering new music (I’ll write a post about this, sometime). However, after a few months of trying the service out, it recommended a song that I couldn’t get out of my head–“The Ridge” by Raisinhill. I had to take it home and figure out what the guitar was doing in the intro:

The C♮ in there is really pretty and I like how it seems to melt into the next chord change (C♯ minor). Note to self, I wonder if it makes more sense to be calling it a B♯ here, since the notes in the key would be E F♯ G♯ A B C♯ D♯ and I see it as the raised fifth (B + a half-step). I need a music theory friend.
