Chaggi is a drastically underexplored relationship, and after 2 seasons of the show it kind of feels unsatisfying. I really hope we'll catch up on this in future seasons though!
See, there are two aspects to Charlie and Vaggi's relationship: their feelings for each other, and their shared investment in their goal.
We know all about Vaggi's feelings about Charlie, she had a whole song about it that pretty much explained it. And we know all about Charlie's investment in the hotel, because it comes up roughly every other episode and is the main plot.
But we DO NOT know how Charlie really feels about Vaggi beyond the surface level "i need you to know i love you more than anything" (which is a statement and not an exploration). The brief relationship crisis we got in s1 was resolved with talking, in fact, about their shared goal: Rosie pointed out to Charlie that Vaggi had always been on her side. We know also that Charlie has no secrets from Vaggi and expects the same in return, but that's still not... like... that could be a feature of a two week old casual dating relationship where one person is bad at boundaries (which Charlie canonically is), you know?
And we do not know how Vaggi feels about the hotel and the whole redemption thing, beyond wanting to support Charlie in EVERYTHING and ANYTHING. Rosie advances a theory in s1 that Vaggi might be looking for redemption for herself, but that's a conversation between her and Charlie that Vaggi doesnt even learn about (onscreen).
So like... these feel like horrible questions to ask and the answers to them should be definitely yes! But the show has not given us the answers yet in fact! DOES Charlie feel strongly about Vaggi beyond relying on her in everything Vaggi lets her rely on her in? DOES Vaggi care about the hotel and redemption beyond it being Charlie's life goal? Is their relationship symmetrical at all?
"Easy" feels like it's telling us that yes, it's all mutual and awesome. But also, it's telling us, not showing. The actual emotional thread of what's going on in it is still Charlie worrying about the hotel and Vaggi worrying about Charlie, and not the other way around!
I want an arc where we explore Vaggi's feelings about having fallen, about Hell and sinners and redemption. I want an arc where we explore Charlie's feelings about Vaggi herself, without relation to what Vaggi is CURRENTLY DOING. And if not an arc, AT LEAST A SONG. The show's a musical, a great advantage of that is being able to fit an entire ass emotional arc into three minutes!!! Give me three minutes each for both of those questions PLEASEEEEEEE
