plot hole??

yea umm this has bothered me for the longest time

but in S4 we see a flashback of eren and zeke meeting in marley and like, theres the whole thing of them discussing the youthinization plan, and then zeke says sm to the extent of "id shake ur hand but we shouldnt come into contact right now" umm why?? like obv cause theyd get transported to paths and like weird shit would happen and stuff, but if they came into contact eren would gain the power of the founder and would be able to perform the youthenization plan, obv eren didnt actually wanna perform it so i can see why he wouldnt wanna make contact with zeke, but why tf did zeke say tht

why did they specifically have to wait till they met on paradi to perform the plan?? it could be done from anywhere, it just doesnt make any sense

by extension of this, even eren should have wanted to touch zeke then, cause well, hed gain the founder, hed take his founding titan form, and obv the wall titans werent around but he should be able to control em from far away i dont see why he wouldnt be able to, even if he cant, just go to paradi, get them and pull up and fuck the world, simple, although to be fair with eren u could argue that since he saw the future he knew the rumbling was gonna happen, and it wasnt gonna start in marely so he let it play out that way since, as he said himself, the future never changes but that still doesn't explain why zeke didnt want to make contact with eren at that point
