My headcanon: After years as unmoving stone even the results of residual nausea from the transition back to flesh is a welcome and pleasurable change.
EDIT: Is Marks for Effort the source of the 2-D image you used to make the model, which you then commanded to be used for “vomiting into a toilet”? I can’t see anything else here that would make it specific to that episode.
It has been a long time, but I think, it’s the pose that comes from there.
