They will all see him, rayleigh is sabaody, garp is retired from the marines, he is only an instructor.
And i don't see a point of shanks dying.
Well Shanks dying at the hands of Blackbeard would completely fuel Luffy's anger, also with Blackbeard killing Shanks there wouldn't be a Luffy vs Shanks which makes sense since I doubt Oda would have Luffy ever give up his Strawhat unless for two reasons. (1. Pass it onto the next generation of Pirates (2) Placing it on Shank's grave at the EoS)
As much as it would probably suck but Shanks dying makes a lot of sense plot wise considering Blackbeard is going to be either Luffy's EoS fight or 2nd last and Shanks vs Blackbeard is a certain at some point in the future.
Also if Blackbeard beats Shanks and Luffy beats Blackbeard Luffy it can be seen as Luffy surpassing Shanks which would be a lot better than Luffy fighting Shanks as it makes no sense.
I suppose it'll be like Ace, even though Shanks is boss character his death would make the story a lot more interesting and entertaining not to mention it'll show Oda isn't like both Kishi and Kubo who are afraid to kill fan favorite characters.
Uh idk Shanks dying by the hands of BB seems pretty cliche to me :l
I don't know how I'll handle his death
Meh, depends on how you look at it. Shanks surviving while seeing Luffy being Pirate King and everyone being alive and happy for him seems a little to cliche for me.
Shanks death wouldn't be cliche so to say I think it's more the fact that it's quite predictable in a good way due to the hype Oda is giving us around the whole Blackbeard Pirates vs The Red Hair Pirates.
I'll probably cry if/when Shanks dies especially if Amv's are made around it.
