inspired by a friend's comment regarding the recent episode:
We know Dollhouse employees have imprints on file (Dominic and Topher being ones we've seen)
and we know Sierra and Victor have feelings for one another, no matter what they are imprinted with.
....so what if Sierra is given Adelle's imprint and Victor gets Topher's imprint again?
("oh yah, fun happy times times eight" says Topher!Victor.
("I don't talk like that," Topher muttered.)
