Re: AUDIENCE
Adora and Catra were absolutely there! They had lots of people to support - namely Richie, Atreus, and Jake! Adora would have made sure they got all got flowers (Idk what kind, feel free to assume~) and hugs and "omg you were amazing!!!"s.
Alex probably also got Lena to come with her to see Richie and support Mobius/Loki!
