If I had some kind of awesome powers then yes. I'd want to be there all the time.
Way more fun than this football game I'm watching right now, that's for sure.
But if I was just me, sans powers. . . well I'd just die wouldn't I? Especially since I'm so awesome and I'd totally be a fan favorite that's also a minor character . . . 😀 And Joss would be all, well we wanted to show that we aren't afraid of killing off well liked characters . . . "blah blah blah"
Or I'd be so popular that I'd have completely insane things happen to me, like in that show Misfits, and I'd suddenly have a ridiculous super power. . . And then I could stick around.
So to sum up and actually formally answer the question, if I was actually able to help in some way, I would want to be there, fighting the good fight in like, every scene, but if I was a useless waste of space, well then I'd rather stay here where I can do some good.
Your threads are always awesome by the way
