I would take 2 and then graciously offer it to Sheridan so that he and Delenn could sit together (while expressing my outrage that whoever came up with the seat arrangement didn’t put them together from the start) and then I’ve got Vir and he’d probably let me choose either window or aisle depending on what I felt like.
(I usually do choose aisle, because it avoids having to get past anyone for bathroom breaks. My goal on any flight is minimal interaction with anyone else. And even though I’d be right in the middle of whatever volatile interactions are happening between…. everybody in those two back rows, they’ll be too busy with each other to bother talking to me. And I will have gained goodwill with Sheridan for getting him out of the middle of it and making his flight significantly more bearable.)
