I was thinking the same thing especially from TV Shows. We should limit there as a way to allow us to expand our storylines more with other writers.
And then the main limit, I tend to get carried away. A limit is NOT a bad thing for me in the least.
Probably no more than 2 per fandom (for direct interaction) and 3 or 4 in total to start?
I have a TON of supe characters. My favorite genre.
I am definitely thinking end of Bitten when Wolves are scattering. Elena is the North American pack leader in general. And coming to Louisiana she realizes she's not a lone female wolf anymore. More few and far between, hidden.
But True Blood, just starting my rewatch. So, I will leave that side up to you two.
