We’ll see more of the other Magellan USA characters later in the story (including the apparently quite popular Glom!)… but for now a brief recap of Gola’s situation. She is, of course, referring to events in the Bad Karma storyline where Miasma trapped Gola in an illusion where she believed she was in a Moscow bunker with an injured Magellan back in 1972. See page one of this story for relevant links.
When I first envisaged the character of Twilight/Turquiose Moon I had her pegged as friendlier and more open, but that has not been the case. I think it makes more sense for telepaths to be somewhat closed off and guarded, given the chatter in their mind from surrounding minds and thoughts. So yeah, Twilight is depicted as a lot less friendlier than I thought she would be.
