Rumple dies and we get baby [Mr Gold’s first name] which is how the writers reveal Gold’s SB name if he actually has one.
I’m wanting to say that Bobby did an interview once where he said that they’d told him Mr Gold’s first name from the beginning? Buggered if I can remember where I saw it, it would have been a couple years back at least, but I’m reasonably sure I’m not just making it up?
Belle probably won’t give birth until sometime near the end of the season, right? I haven’t paid enough attention to notice how much time’s been passing since she found out she’s pregnant, but it’s not long so far, is it? And S6 is picking up straight away without a time jump? So if this season spans several months, then it could fit for Belle to give birth in the season finale or there abouts? So if Bobby’s told them this is gonna be his last season, they could kill off Rumple just in time to name the newborn with his SB name for the big season finale.
