Hikaru gives a short, still slightly confused, laugh. He doesn't really understand why someone would want a cute bacteria, but if someone did then Emily would make sense. He does know how it is, too.

"In happier news, though - I've only managed to find my way into one projection, but it was a pretty interesting one. You know the sisters? It's looking like the butler really did do it. We had this sign that said 'Finish the job', and there were little puppets of them that killed this old guy puppet."
The way he says it, it sounds like he thinks that's pretty cool, rather than anything concerning or upsetting.
