I'm exhausted, so apologies if this is brief and nonsensical.
Thomas, Katie and Justin will all be there and fighting. Thomas will use a lot of unforgivables - particularly crucio and ak as they are his favorites. Katie will... kick some Death Eater ass, she says. Justin will do whatever he can/whatever is needed.
Meghan, sadly, will not be involved in the battle since she has no reason to be there or know about it, but she wants me to say that she will be very PUT OUT if anything happens to Oliver or Penny. :(
Also, I am up for ANYTHING - yes, including deaths - happening to any of my characters during the battle. I'm a fan of random dice rolls to decide these things, so feel free to use and abuse any of them however you need/want to.
As far as the reboot, I don't hate the idea. I don't have futureness planned for any of mine currently, though, so I don't know how easy it will be for me to play them 5 years in the future or what have you, but I'm certainly open to it (as well as open to plotting things out if anyone wants to do that, should the reboot be decided on as a go).
I know I haven't been around lately, real life kicking me in the ass, especially my sinuses, but I'm going to try to be better. :)
