Age. Genetic variations can produce different aging patterns. Like Patrick Stewart always looking like a healthy 60 year old his entire life, then Renée Zellweger who aged worst than a lemon that laid in the desert for 20 years. Keanu reeves who wont age at all because Gary Oldman drank his blood till near death then pissed in his mouth. It depends on who it is, how they lived, and if they drank vampire piss or not. That’s the extent of my knowledge on this issue.
he told a different version of this story where they were sitting in the makeup trailer and his dog came into the trailer... i doubt either are true... atleast tell the same lie
