Wilson was still tired, suffering the after effects of the very
disease he'd spent the past 18 months battling in Uganda.
It had come as a nasty surprise to both himself and his fellow physicians when Wilson had begun to show the symptoms of HAT(Sleeping Sickness) since he was innoculated against it. With Aziraphale already reassigned it had been up to Wilson to ferret out the cause of his innoculation failing.
One of the many Pestilence demons that Aziraphale had been battling in this unstable country had made an oppertunistic attack upon Wilson within days of Aziraphale's reassignment and reversed the effects of Wilson's innoculation. It had taken everything in Wilson to hold it together long enough to banish the demon after which he'd presented himself for the still toxic treatment regiment that their little hospital could provide.
He'd refused the newer treatment due to the lack of funds to replace what would have been used. He was healthy -at least he had been before the attack- fairly strong and had a back-up in the form of a guardian angel if need be and the people who came to the hospital were often the old or the young who needed the extra care from the newer medications.
So for 72 hours he'd been under the influence of the toxic medications despite their unstable reputation and now that he'd come out of the symptomatic coma, Wilson decided it was time to call Aziraphale.
He knew his beloved mate was just gonna love this.
