He considered it. It was very tempting. But in the end... what good would it have done? Susan wouldn't want him to do it. Hell, if she'd popped out of the woodwork and he hadn't left the house in four months she'd probably have slapped him. So he forced himself to get his boots on every day and do his damn job. He found lost things. He worked on improving a few of his foci and enchanted objects and stuff. Cries most nights, but doesn't admit it, and that's been getting better. Recently he took a job protecting some kind of monastery from monkey demons.
A factor relevant to that particular job is currently napping in his coat pocket. He found the puppy there afterwards and tried to call that monk dude, but the monastery seemed to have vanished. Which was weird. But he got the puppy vetted by Bob and Father Forthill, and they said the little guy wasn't some kind of hellspawn, so... he kept him. Called him Mouse. Let him nap in his coat pocket. Mister got along with him, because Mouse wasn't big enough to be a threat to the big cat's authority.
Anyway, Mouse is napping in his coat pocket, and Harry just got out of the morgue looking at a corpse. He's pretty sure this is the work of some White Court bastard. The victim doesn't have a mark on him, but he's got the dopiest grin in human history. And Harry, being Harry, knows from dopey grins. So Harry sets out looking for a White Court vampire. Thomas doesn't know of any of his cousins who'd have gone after this guy (their official victims are dumped in a nearby quarry, apparently), so he's out investigating the red light district. And trying to look like someone who would be interested in a prostitute, instead of someone who would rather cut off his testicles with a spoon than lay a finger on a member of the oldest profession.
"Don't worry, I deserved it. I'll see about introducing you. So, do you want to go back to the apartment?"
Harry leads him back to what could charitably be described as a "vintage" Volkswagon Beetle, and could be uncharitably described as an absolute wreck. "This is the Blue Beetle. It does its best."
"The Blue Beetle is not 'cute!' It is a valiant warrior in the battle against fuel efficiency." Harry gets into the driver's seat and, after some effort, pops the passenger-side door.
"The other adjectives are disallowed. Love is acceptable." Driving begins. Chicago traffic is Chicago traffic.
(Mouse is belligerently napping in a buttoned coat pocket. He is in time-out.)
"If you start wearing a big fuzzy sweater around all the time I might have to call you Velma, fair warning."
"Koala works. D'you want to be Koala? I'll call you Koala. Captain Koala. Or just Koala if you want."
"I don't wanna be Koala. Well, maybe I wanna be Koala. I'll think about it. You can keep trying in the meantime, all your nicknames are fucking delightful."
