I never really knew the reason Zidan left. I figure Ralph was leaving a lot out, but jesus. I legit feel bad for Gator. I've had had family abused by a manipulative friend so this hits close to home.
Gator, you can still take Zidan's cue. You're at a crossroads in your life. Zidan left this behind because he saw the writing on the wall. You know Zidan made the right choice, so make the right choice for yourself. If you're not happy with your life now, I guarantee part of it stems from your parasitic relationship with Ralph. Sever it. At the very least, it's less shit you have to worry about. You won't have to tard wrangle a guy who's continually digging his own grave.
As funny as it is and would be, you don't have to join PPP's sperg circle-jerk either. Just step back from the Killstream and focus on yourself.
If you're worried about what would happen to Ralph without you, don't, he's not your responsibility. Ralph continues to dig his own grave, which he will ask you to pull him out of.
