Q: Can I use the Flee! upgrade’s action to make a Move action with Skritch and an adjacent fighter, regardless of the tokens they have?
A: Yes, as long as you have a way to take the action on the upgrade card (i.e. Skritch doesn’t have a Charge token, or you have a way to grant him an action regardless of whether or not he has a Charge token).
Q: Can I use the Flee! upgrade’s action even if there is no adjacent friendly fighter?
A: No.
