PariahPoet: Cute picture!!
Now to topic, yes it's been discussed in bits and peices here and there, but it seems as though we're talking here right now so I just love adding my two cents. I really can't tell when a werewolf would first start shifting. For some reason they all seem a tad unrealistic to me, but we are dealing with something unreal in general.
The puberty thing seems to be placed as an answer, and I think in the past I have myself settled onto saying that hormones activate it. Yet I don't know what hormones start the virus or start the just the shifting, and how would that work for older weres who don't have a rush of hormones? I think the main reason people like this is because becoming a werewolf is so the ultimate symbol of puberty, just even more hair and more change the the body, not to mention 'primal urges', so people seem to love torturing teens with becoming a werewolf!
Babies, I just find it weird, though cute, for babies to shift. Would their body handle it or be able to fully shift? I just can't even see a little two year old turning into a cub, though it would be cute.
Hrmm.....*shrugs shoulders* I dunno.
