Tracy and Five hate eachother, always have. and possibly always will
Five disappeared for 16 years, and when he came back he was in a 21 year old body (so it's not weird, and he'll be 29 and not 58)
Five hates Tracy because she gets high all the time with his brother, Klaus, and he doesn't like it.
When Tracy found out, she begin to hate him
Five hating or disliking someone, wasn't surprising, He's cold hearted and he does not care about anything
which is also not surprising for Tracy because she is the exact same thing
so what if its meant to be?
but what if there, cold hearts get in the way?
