[Well, unless there's more physical evidence to link the two, say, the fact that the stand looks like it was sliced up by Ciel's preferred weapon sitting around out in the open...

Otherwise, Tachikoma will just figure it happened before Ciel arrived on the scene.]

I guess it doesn't, but I'm worried this was done by someone lashing out, and if that's true, they might lash out at other things, which could be dangerous to them and those around them!

At least it looks like no one else was hurt here though...
