i dont get it why was everyone forgeting xion is it like she never existed so time reversed and erased her from existance or is something more in depth......????????:huh::huh::huh::exclamation:

Well Namine said that once Xion disappears, everyone's memories will too, or at least eventually since Roxas and Riku still remembered her after she faded.

i think when she died the memories in her returned to sora and all the memories related to her dissapeared .she was faceless but as she started to hang out with roxas the memories in him became a part of xion so thats why she looked like kairi. so when she died the memories probally dissapeared so roxas doesnt remember her. that or no one really likes xion so they forgot about her o.0 i know i do

Yea, since she dissapeared the memories created from when she was "alive" went into Sora with his other memories. The reason he doesn't remember her is because,

 

1. The chains that connect those memories aren't there

2. Even though he could remember her somewhat if he tried, he doesn't know he should or could so he doesn't try

in 358/2 days namine cant piese(dam my spelling) his memory back togther untill everybody forget's xion

Xion built herself on Sora's memories. Because the memories went back to Sora no one can remember her, seeing as those memories were her whole being.
