Hello! I'm Tracy and this is Mick (Sean McDermott really, but mostly he goes by Mick). We are both from Northern Ireland (GMT!) so I will apologise now for swearing and accent creeping in ;D
Mick grew up on a farm, and was a paramedic pre-pulse. He'd gone on holiday to the states when the Pulse hit, and he hasn't been home since although you wouldn't know to listen to him since his accent's still pretty strong. Now, he's Buck's second in the Oma, which he quite likes. He's a chatty sort who'll talk to most everyone he sees, and he likes to joke around, but he has an absolute bugger of a temper when it's triggered. There's more details in his app if you're interested.
If you wish to work out plots or whatever, I have a contact post here or I can be grabbed in the AIM chat room thingy (AIM name: SayNoToZombies)
