Hmm, GREEN tea is a given, MINT tea is very likely, the only other option i see is GROUND.
"Superdeath seems to have acquired a rep for aggression somehow.

GREEN and MINT are pretty likely. After that I'm failing to make any connections. Perhaps WASHINGTON, due to that american revolution event, where they threw the tea in the sea. Does that have a stronger connection to WASHINGTON than I'm giving credit for?
After spoilers: GROUND as in shredded leaves? I can see it as well.
I am only familiar with tea bags, but I guess you could make it from ground leaves.
Would a PRINCESS drink tea?
I don't like WASHINGTON, I don't think he was involved at all with the Boston Tea Party.
