Is Grey a thing in this context, really? I'm not up on my Star Wars stuff. It's not a school of teaching, is it? Or is it more like a neutral mindset, not a rigid school?
For me, I guess I'd go other. I'd use my fledgling powers to wander for a while, see some of the world. Maybe help with some big picture stuff, like feeding the poorer countries, or whatnot...
I'd leave my Fiancee, as well... It would kill me inside, but I would have to. I guess I'd be trying to divert attention from my loved ones as quickly as I can, actually, because it wouldn't be long before I was hunted by some group or another. I'd be terribly lonely.
Could I use my powers to communicate telepathically? Then I might not be so lonely, and could stay in touch with my loved ones. I'd tell them I was sorry.
If I found out they were hurt in any way by people looking for me, I'd lose my mind.
If my fledgling powers hurt them in any way I'd never forgive myself, probably shut down completely.
I keep picturing the video to Titanium by David Guetta.
But, you know, with a bearded, fat 30-something in glasses.

Jeez, this is all sad! I thought getting kick ass power was a power fantasy. I'm not doing this right...
