I'm tempted to have this bit in 2nd Season where freakin' Alucard from Hellsing shows up, and the Tsukimura family quietly freaks out because he is one of these progenitor vampires that Shinobu is talking about - one of the "True Monsters" that gave rise to their kind.
Alucard would be amused by their fear. He doesn't think it's becoming of them to be living such a civilised lifestyle, but he does feel it's better than going around and pretending to be monsters - they at least understand what the "True Monsters" are capable of. For that, they would have a modicum of respect, and offers to take Shinobu and Suzuka under his wing so he can show them what they are truly capable of. At the very least they might be able to help Seras come to accept her vampirism with at least some grace.
