Sans has always been able to remember past timelines, for as long as he could remember. Never before has he been able to find a monster to confide in, to relieve the pain that echos through his mind at night, the memories that swallow him whole and torment him in his everyday life. That is, till now. (that was a lame description..) Undertale =Toby Fox Credit to original artist of cover, its freakin' adorable. I'm still smiling looking at it.
