I don’t think Gold would react that way, honestly…….In S2 finale, he was handling Neal’s death relatively well, thanks to Belle. Belle’s death, IMO, would be the one to throw him in a tizzy, making him break down and lose it because his TL would be gone – and as much as he loves his son, Neal is not his rock or anchor or emotional center. Gold can get through Neal’s death with Belle supporting and loving him, but without her…..
I really don’t understand this theory that Gold kills Neal at WW’s behest. For one thing, MRJ was scene filming in SB. For another, while Regina did tear her father’s heart out, at least it was her choic. Forcing Gold to do that to Belle or Bae would be disgustingly brutal and completely cruel….. Lastly, IF he dies, I think he’d die for Emma and Henry. All of his spoilers have really been about them……..It’s Belle who we think is involved in Gold’s story.. I think that if WW were to demand he hurt or kill anyone, it would be Belle. In my fantasy, Gold’s love for Belle overpowers the magic of the dagger and……… That’s just my fantasy though; even if it doesn’t happen, I still don’t think Neal or Belle or whomever will di at Gold’s hands
