It's not a seal if he's not sealed.
Question edit: Does that really matter for a Trance, though? I was under the impression Trance drew on residual energies to make things happen. If it's not that and you just needed to get dosed by it to work, then there'd reasonably be a "time limit" lockout sort of deal for anyone prior to 3.4 to have experienced it.
I didn't do SMN quests, so I don't know these things: Is it enough to just get splashed by aether or do you have to knowingly manipulate it at the time?
