Lucifer was brought to a meeting with the overlords (despite not being one, and being of higher status), when the meeting ended, everyone obviously left. But, unfortunately for him and the Vees (Vox, Velvette, and Valentino), Carmila locked the door when she left, leaving them stuck in there.

Lucifer: what the-tried to open the door-ugh, locked..he tried kicking it down, but didn't didn't work (somehow)

Vox: Val, can you shut up for a bit?!

Val: tch, you like it when I talk though, Voxxie~~

Velvette: you dumbasses, were all stuck in the dam room...with Lucifer!

Lucifer: I don't wanna be here. 🥲
