I don’t think Robin’s potential death would have any real payoff except to send Regina spiraling back into villainy, (much the way Neal’s death served to return Rumple to his villain status after he’d striven so hard to save everyone form Peter Pan). I don’t find that kind of character regression very interesting. If the main reason to kill off Robin (assuming he dies) is just to send Regina back over the edge or to make her suffer, it sends a terrible message that characters who are essentially good parents aren’t worth keeping around.
Agree with you about Regina, but not about Rumple, after 315, everyone simply pretended that Neal never existed, except for the once in a while epis where they need to bait Neal and SF fans,the thing is on those epis Neal was used as a link to Emma and lately to Henry. Was never seen or mention on interviews that Rumple became evil bc of Neal’s death, is canon on the show and interviews that they say Rumple just wanted power the same way they made rumple retcon why he hurt himself, the been trying to erase Neal from Rumple life. But I do see them using Robin for Regina with the Sq bait, by making Emma be in Regina side, trying so save her from becoming evil, blablabla. But since they can change ideas maybe Robin doesn’t end dying and this is Neal s2 mix with Archie storyline all over again.
But in the end what we have are confusing filming spoilers, bc the fact they are filming 3 episodes at same time, makes a little hard to try to make any theories or even separate epi spoilers bc in the end we don’t know which spoiler is from that epi.
