What would Rook do if Ben lost his memory? When Ben don't know who he is,Ben think Rook is enemy or something?
Sorry it took a while, but thanks for asking!! :)
I believe with prior events of the ‘Albedo incident’, Rook will be more aware this time. He will know something is wrong with Ben like in the episode ‘Ben Again’. Firstly, he will assume Ben is playing some joke, depending on the situation Rook will also think that some baddie has done something to Ben’s mind! With no idea on what to do he would then bring Ben to Plumber HQ. Throughout the day, Rook would do things to try and trigger Ben’s memory, from trying to play Sumo Slammers with him - reading Ben his Plumber files - to stuffing his face in chili fries. Most of the time nothing happens, which is so sad…
Ben obviously with no type of memory of who he is or who Rook is will be in a panic. ALIENS ON EARTH?! I also imagine Ben constantly and accidentally activating the omnitrix which freaks him out even MORE! He will be very scared and hesitant towards everything, he even cries when Rook tries to take hold of him, but after a very looooong explanation… Ben caves in and follows Rook around like a child.
Ben Believes Rook is an Enemy
I feel like as the day goes on one of the bad guys would manipulate Ben in his vulnerable state. For example, Will Harangue, some-how some-way he would convince Ben that the Plumbers cursed him with the omntrix and that he’s been actually fighting the aliens, etc. etc. a bunch of bullshit that would all make us all flip a table lol Which all in all, causes Ben to transform and attack Rook. After a long heated battle, Rook would pass-out. Ben about to make his final strike *FREEZES*. Why you ask?! Because of MUSCLE MEMORY BAHAHAHAHA! Then Ben beats up Will and Ben takes Rook back to Plumber HQ -w- Where they both sit in the hospital bed curled up and snuggling ♥ Ben of course regains his memories~
