Emil and Daniel

[Froge]

Alexander may have "farmed" Emil; i.e. feed him some vitae, keep Emil alive longer to torture to get more Vitae for himself, etc.

As for Vilhelm, maybe the air or some chemical substance down in the Wine Cellar kept human organs preserved for extended periods of time. What's more unrealistic is the fact that in the flashback, all of Vilhelm's men were speaking english. "Alexander, you piece of shit!" <-- SO 1700s speak
