[warning: many pictures]
Okay, so earlier in the series, Frankenstein has an altercation with an artificial vampire named Jake. Jake is confirmed to have enhanced healing that can regenerate enormous lacerations in a couple of days.
Several days later, Mary (a fellow artificial vampire) and Jake say this regarding Dr Crombel's arrival (the man who created them)
And when he arrives, and performs an examination on Jake, Dr Crombel has this to say:
He states here that despite Jake's increased regenerative ability, his lacerations are healing at the rate of a normal human, as a result of the bizarre properties of Frankenstein's aura.
Additonally, one can see in picture 4 that, despite several days having passed, the lacerations given to him are still very severe, and have only just slightly begun to heal.
In additon to THAT, we have a later dispute between Frankenstein and a transformed Mary, which shows that further exposure to Frank's aura can reopen wounds given previously.
And thus concludes my evidence presentation. (whew that took a while!)
