After being yelled at by
Ragnar, Guppy spent a little while hiding in the toilet*, before hunting around unsuccessfully for Sinric, and finally returning to the infirmary to find out who dropped the ball in terms of watching Athelstan.
He was ready to give them a bollocking, until he discovered that one of the junior rats on duty was also missing. A quick search revealed scrabbling from behind one of the pieces of equipment, where the junior rat had fallen off. At least they hadn't mislaid the patient because they were mucking around.
Guppy not being a vet, he carefully scooped up the little guy, and has brought him back to the main bar in the hope of finding him someone who is. He is still visibly shaken, but he at least has the task of bathing Asclepius Jr's leg as a distraction.
[*Which did not entirely help with the accusations made by Ragnar]
