maby because at the end of sly 3 sly only pretends to have amisia so he could be with carmelita, you can tell this is true because if you see the credits at the end when sly and carmelita are on the balcony sly turns and winks at Bently. if he actually had amisia he woulden't have reconized bently so he wouldent have winked, you see where I'm going with this???............ Yore right but I think they they will be married then Sly like just disapears and turn back to bentley and Murray(this is just what i think) no sly and carmelita do not get married at the end.
he is so kind and ppl love him for his honsty and for his caring for the fans he is popular for his FNAF series TINY BOXTIM/WILFORD WARFSTACE/SOME OF THE PLIERS LIKE GOOGLEPLIER/SLENDERMAN/AMISIA A LATE NIGHT DRINK/VANISH/DARKIPLIER are just a few to name
