Oh heck yes. I always thought that if I can't have Donna/Kori or Donna/Kyle, Donna/Jason is just incredibly interesting to me. Their entire pre-death interaction was so caring and nurturing, and it's an interesting contrast to what's going on now. Donna seems to disagree with Jason a lot and think he's generally just a jerk (and is able to kick his ass), but has that sincere worry for his well-being and seems to get along with him quite well when there's no Kyle around.
Countdown should have had WAY more complex interaction between the two. I hope they interact in the future, really, because his crush on her is actually very touching to me, considering how motherly she is.
