In many of the Star Trek's, the holodecks are used by only one or two people. Why can't they just be shoulder to shoulder in the holodeck having different fantasies?
Or maybe just turn the holodeck into like an open air brothel, to get them maximum number of crew member some relief.
I think her surprise is the least believable thing about this scene. Any captain would know that the cum filter gets full quickly and needs to be cleaned out.
Back on the Enterprise they'd just recycle it into Data's cum tank. I haven't seen lower decks, is there an android that comes "fully equipped" in this animated series as well?
