Tattle was concerned that Ten might have had something on the Admiral, in which case, some… intervention would have been in order. Cuz Tattle and Admiral Maev? They go waaaay back. And you look out for people you have that much history with.
For now, Tattle’s going to take Ten’s word that he’s not involved in that suspicious series of events, and is thinking of involving him in an equally ludicrous and potentially dangerous new situation. S’gonna be fun.
