Decay
In season one of True Blood we see Bill nearly die from exposure to sunlight. I estimate that it would take a total of 250 seconds of exposure to kill Bill.
In season two of True Blood we see Godric commit suicide by watching the sun rise. It takes 30 seconds before death.
Why can Bill take more light than Godric? I propose a theory.
It is a well known fact, across nearly all vampire mythos, that the longer a vampire is alive the stronger it will get, and this has been established in True Blood as well. However, I theorize that it is not the vampire getting stronger with age, it is everything that makes a vampire a vampire increasing in intensity. Meaning that as a vampire’s speed and strength increase with age, so do the weaknesses associated with being a vampire (namely, sensitivity to sunlight).
Vampire Bill was 144 years old at the time that he was exposed to sunlight in the last episode of season 1.
Godric was 2100 years old at the time of his death.
Age of vampire (yrs)| 144 | 2100 |
Sun Exposure (sec) to death| 250 | 30 |
Using these data we can extrapolate the age of a vampire if the time until death due to sun exposure is known (and vice versa).
One of the most memorable sun exposure deaths in all of vampire lore is that of Count Orlok (Nosferatu). His time til death was a mere 5 seconds. So where does that put him in number of years?
Approximately 3753 years old.
