In the mission "Citadel: Wounded Batarian", you encounter and speak with, well, a wounded Batarian named Ghorek. The guy's pretty beat up and only has a "50/50" change at survival. You talk to him a bit and then are given the decision to put the fella' down quickly or let him suffer awhile. Neither of these choices seemed particularly good.
So I'm wondering, is there a third, non-obvious way to proceed? Is there an obscured path in game that allows you to aid the Batarian and restore him to health? If so, what rewards does that route yield? Also, does it affect any further story threads?
