I wouldn’t be sure sure about…
…because I’ve seen an Instagram post captioned ‘Make way for the Valentinos 
’ (Valentino was Alucard’s last name), the account is by a Sapphire and the account has over 33k followers with people commenting on the post how much they can’t wait for the return of her story 
The post is a photo of Alucard & Muriel together in what appears to be a security office (that sort of background & pose could be linked to mischief or upcoming choas if you analyse the body language/behaviour of the photo) (:
