Gonna be honest with you team, maybe I'm just not caught up on my Doctor Who® Alien Babies® lore, but I was a bit confused by this one. Why do the weeping angel cherubs have potent acidic milk? It's not logically impossible but it feels like something of a non sequitur. Shouldn't they have, like, quantum locked stone milk, or time milk, or whatever? Gonna be pondering this one for a while.
