Alice inviting Sam and Celia to the show seems less like trying to fuck w Sam or his relationship (or even flirting w then both) and more like she's fucking lonely. she might have genuinely wanted them there, cuz, y'know, hanging out w people is how you make and keep friends generally. like,,,, before Celia it sounded like Sam and Alice were chillin' at work and had regular banter but since Celia showed up Sam's attention is all on her and hes started treating every interaction with Alice as an annoyance (and just generally being grumpy, if you consider his interaction w Gwen that one time). plus it's not like Gwen has time for Alice to even mess w her anymore. everything is changing and I don't think Alice is taking it well
