I’ve caught some very strange Halloween vibes and remembered, that Humans are the most dangerous and unpredictable creatures in the GFFA. So, ironically, Thrawn made himself Human for Halloween. Eli didn’t get the irony, but decided to support him… in a way.
PS. Faro is not impressed. At least she tries to look so, but in fact she might be needing to change her pants. We will never know.
