Okay, I know Seb’s an ass at this point in the season
look at how he looks back at the other warblers so he can laugh with them
but they just look horrified because they love blaine and kurt and this isn’t something they’re feeling good about
so Seb’s smile goes from this big shit eating grin to a more subdued smirk
and there’s just something so tragically lonely about Sebastian.
^^ reasons why I wouldn’t be opposed to seeing Seb in S4.
