Nicholas never exhausted any planets this round so he has nothing to do for the Secondary Ability of this Strategy Card.
Steve also has not exhausted planets.
Everyone has exercised the option to play the Secondary Ability from the Strategy Card Melissa chose. She flips the Strategy Card over (Inactive) but leaves it in her area.
The game turn resumes with the next player action in order as specified by the numbers of the Strategy Cards.
Proceed with Nicholas.
