Could Vayne's upcoming encounter with Evelynn make her bats canon?
This is some solid tinfoil here but we all know Vayne has a bats particle effect when she tumbles. This isn't exactly explained by her lore as Vayne is strictly non-magical and bats are almost always a sign of the occult.
We also know Evelynn killed her parents and is currently being hunted by the Night Hunter.
But what if, upon encountering a source of evil as potent as Eve, Vayne gets tainted in a way that sends bloodthirsty spirits and dark creatures after her?

Perhaps it isn't even a Berserk-like brand that draws adversarial entities. Maybe it completes the "he who fights monsters" trope and Vayne is now somewhat enhanced by the touch of magic, which explains her superhuman speed and bullshit damage. Maybe she is forced to live with the minor change and only utilises it further in the pursuit of her foes.
What do you think?
EDIT: yes I know her entire deal is Batman Helsing but that's not a valid in-world explanation, is it?
