the whole trip back to erid rocky can hear grace's heartbeat and then suddenly he's required to go down to erid to discuss really important things like the taumoeba and grace biodome which are important and he and grace agree they're important and that he needs to go and they'll both be okay and neither of them will die if the other one can't see/hear them for five seconds
and then the second rocky can't hear grace's heartbeat anymore he has twelve consecutive panic attacks
