Just otters and slugs. I don't think I'd like to be in the water with the slugs. [That's not what Kel means, of course, but it does seem like an opportunity to inform Kel about the potentially unpleasant wildlife that's around them. Nagito is referring to ottas and swamp slugs.]

I don't think I can help you with figuring out the best thing to say, though. I'd probably start with "can we talk about your murder."

[Good to know it was a murder, though!]
