as she is the mother of his child and suffered due to be horribly burned. Once the truth comes out that Valentin did this--I don't see how they haven't painted him into a corner here. Sonny will likely put out a hit on him if he doesn't throttle Valentin himself.
I do agree that long term villains are needed but GH seems to consistently paint them into corners. We've seen it time and time again and never more evident when said villain goes up against: Sonny, Jason, and Carly. The results are either prison, leave town, or death. It will take a miracle for Valentin to survive this.
