   Summary

   Simon is pretty sure he's dead. He died in that blood ocean and now he's in some special level of hell made just for him and that godforsaken monster. Why else would he be hearing the voices still? And it's not like he was aquatic before all this, but the tail and ability to breathe underwater seem to be a pretty good indicator that he and that monster are a package deal now.

   Grace is pretty sure there's a merman living in his biodome's ocean. He... isn't quite sure what to do with that information, especially since the guy won't let him get close. To be honest, Grace isn't sure he even wants to get close. After all, the last interaction he had with a living humanoid, he had been betrayed and sent off to die. It's hard to come back from that.
