Eventually one or both of them might need to sleep, but for now, they haven't nearly finished making use of this floor.
Isabella can go without sleep for a week! She does this by default when there are interesting things to accomplish! This is such a thing. It is an open question whether she could sleep if she tried at the moment.
A few hours later, though - maybe if they make it all the way to the living quarters of the ship - he might give it a shot.
Isabella will allow it. As long as he doesn't try to go anywhere she can just as easily wrap herself around him and hold still by way of reminding herself that she has successfully found a mate and is not going to die.
In that case, after about six hours of various exertions, during which time they do indeed make it to the bed, he curls up and wraps his arms around her and tucks his face into her shoulder and naps for a while.
Snuggles. Not-going-to-die-ness. Eventually he will wake up! That will be nice.
Eventually, he does wake up, and immediately kisses her.
Saying she goes from zero to warp instantly would imply that she is capable of being not at metaphorical warp right now, which is false, but kisses increase metaphorical warp factor.
Or not.
It could also be much sooner than that.
It's good if it is sooner than that. Isabella is impatient. She found a mate and now she wants to make use of this exciting finding.
And snuggles. Those too. He's still a little sleepy; it makes him slow and cuddly and affectionate.
Hmmm. Slow. Well, that is okay now that the most urgent portions of the week are taken care of.
And after they've been at it for a while maybe they can go back to being - not slow.
