I think there are some animated Castle icons out there, just not sure they'll be what you want. ;)

I think/hope Beckett had time to run back to her bathroom and jump in her tub (it looked like it was one of those old fashioned steel/iron claw footed tubs) which could have protected her some from the blast. They'd be nutz to kill her off. Hurt her a bit is fine...no kill the Beckett. That would be bad.
