Alex was in a car accident, and he lost his memories of you in the accident and woke up without any recollection of your existence

The only one he recognized are his bandmates Nick O’Malley, Jamie cook and Matt Helders (Your brother)

His distant demeanor had returned, just as it had been long ago when you first met. It was hard to soften him up

You feed him porridge, and he speaks while chewing, "You're pretty."
