We didn't discuss yet which of the two would be the one to get chosen ;)

As Dexter has the characteristic 'scared' when he is sober, maybe it would be interesting if Dawn was the one being chosen and the one to get many people ask her if they would be her partner. He would become jealous and would drink more then usually.

But also: Dawn has the fear to lose a friend and the dislike to being ignored, so she could also easily play the role of being jealous at her partner getting many people ask him to go with him on the trials

I think both are a good possibility
What do you think? ;)
