The Tenth doctor, in Blink, said that Weeping angels are only stone when you look at them. So aren't they just flesh when you blink or turn your head? Can't flesh be shot and killed(Yes, the doctor doesn't use guns, but River does, and she appears in Time of Angels, Flesh and Stone, and The Angels take Manhattan). Also, can't stone by mined? If this is the case, Weeping angels can't exactly live forever, like we're led to believe Afro Circus Afro Circus Afro Polka Dot Polka Dot Polka Dot Afro! 22:35, December 14, 2013 (UTC)

What does stone's mineability have to do with anything? We saw the angels eroded by time but then reform themselves when near a source of energy. And while yes, they're not stone when you're not looking at them, that doesn't necessarily mean that they're flesh, although they would admittedly be likely more vulnerable then, though bullets might do nothing against them anyway (they were used to keep the Angels at bay in the dark once, but I don't know if it was specified whether the bullets would have been lethal or just annoying). And no one said they live forever. There were baby Angels in TATM, which suggests a life cycle. We were just told that the race as a whole has been around almost forever. —BioniclesaurKing4t2 - "Hello, I'm the Doctor. Basically, . . . run." 04:29, December 15, 2013 (UTC)
