I mean like Rodney T. Kirk.
I think they should Costanza (or David if you will) Hemmer back on to Strange New Worlds. He's just back in engineering and nobody should say anything. If anyone complains they can say "This was the story we wanted to tell. We can't be constrained by every detail that came in episodes before. Canon is too constricting to good television."
Didn't they already pull that joke with Shaxs?
