Water trauma buddies is A+. I am all for this. Terezi will probably also tell her that she smells like apples and it's delicious. Good skin choices. She'ss not quite as tactful as Elphaba it seems. :')

Though, Terezi is also a social butterfly who aggressively befriends people. She's just more jarring and sometimes abrasive about it. But I'm likewise sure that their general dispositions will get along famously.

Terezi can tell her all about her acquired distaste for caste systems and the ridiculousness and oblivious cruelty of the Capitol in Panem. And how she has to go back and fight for the people and overthrow the government for Justice. It'll be great. Good times.
