- We defeated a dangerous enemy. Who or what was it?
I'm open to ideas from others. 

- We destroyed our surroundings in the fight. Where was it? What did we destroy?
I like the idea of a containment building being destroyed and villains escaped. Gives us multiple people to fight against.

- We didn't trust each other at first, but that changed. How? Why?
For Psyche, it would be the fact that the others would accept her and want to work with her. It would take time, but eventually she'd grow to trust and enjoy working on the team.

- We saved the life of someone important, either to the city, or to us. Who was it? Why are they important?
Hmm. I like the idea of saving the Mayor. Gives us a nice starting off point.

- We paid a high cost for victory. What was it?
As above, if the containment facility got destroyed, we let loose a bunch of villains. Would also give us a mission right off the back of tracking them all down and stopping them again.

- All things considered, we did well and impressed an established hero. Who was it?
I think I can get behind Double's idea of Silver Hawk. I only hope that Silver Hawk paid attention to everyone and not just Max and Kiante (as in, he noticed all the heroes, not just those two and decided the others were ok at best).
