Yes, I also don't see how the Marleyans were able to capture 7 Titan shifters and keep them restraint til they've found Eldians who shared their cause to pass them on to them since Titan powers can't be passed to Marleyans.

I don't think it was 3DMG though because Zeke was curious when he saw it on Mike and surmised that the wall people must have realized the nape is the weak spot since they're using swords.
