I'm guessing it has to do with Lab personnel in general:

1) Barry Allen, day shift lab tech, is currently day shift supervisor out in the field.
2) Greg Sanders, until recently night shift lab tech, is now a night shift field op.

That leaves a temp substituting on Day shift, and a FNG on night shift...

Of course, I could be wrong, but I'm hoping for a no-prize :)
