A Dues Ex Machina would be if the Team just found a button which when pressed, blew all of the aliens up, that would be something that wasn't explored previously. Failsafe wasn't a Deus Ex Machina, because the plot was alluding to the resolution throughout the episode, with the inclusion of Manhunter and the Team not being sad when their mentors died, etc. etc.
