My comment on Bart annoying Wally is just to provoke him to rejoin the team once more. Just a thought. And Bart Altering the time stream I understand it but can't put in words.

Is like having 2 dimention one altered one went forward and not even affecting Bart & Neutron's memory.

Can someone clearify this how and Y with logic pls.
