Send Tim to college.
Absolutely everything that made his Robin run work because it seemed abnormal and special in high school is not only normal in college, but ramps up to 11.
Some things from my college experience that would work, and I'm sure other people have similar crazy stuff happen:
-The student senate leaders, president, and other officials have started a counterfeiting and money laundering scheme using the funds that the various student clubs pitch into through their fundraising. It's when they pay off all their debts before graduating that they get caught.
-The head of the economics department is running a drug and alcohol smuggling operation into dry regions of the state.
-Cults. Various kinds.
-Serial rapists.
-Serial killers.
-Homeless people building camps in various places around campus...including the library.
-People getting pregnant for financial aid.
-Alcohol problems galore!
-Ravens deciding they don't like certain people and making their life hell.
-Research animals being stolen/released. Including deer during hunting season.
-Being late to class and finding out that they randomly decided to move ten minutes in because it's a gorgeous day and having to find them for partial attendance credit.
-It's a gorgeous day and multiple classes are getting ready to fight over the best outdoor classroom areas.
-Car thefts.
-People breaking into dorm rooms.
-Various drug operations that are being used to make tuition and you don't have the heart to turn them in because they're really nice people.
-Fruit fly infestations because the freshman at the end of the semester release their into bio projects instead of killing them. (I too was guilty of this, they had good personalities, those flies.)
-Sledding accidents.
-A new safety supervisor is hired, learns that the sledding hill is called death hill due to multiple deaths and students are regularly treated for concussions, fractures, and internal injuries. Being reasonable, he fences the hill in half. Then experiences protests that border on riots, death threats, and finds an IED under his car. The fence comes down.
-Christian groups protest the condoms in the welcome new student packages and the almost daily sexual Sunday events during September. The next year there's no safer sex education or supplies offered. One in two freshmen is diagnosed with an STI, one in 3 high school students in the surrounding area, and one in four middle schoolers, and the epidemic wave is easily traced back to the freshman dorms because it's not affecting upper class students.
-Someone met a girl online, thought she was 17/18 and needed a place to stay because her parents kicked her out and smuggles her in to live in his dorm room. Then she seduces him and his roommate. Afterwards, they find out she's thirteen, and has been reported missing with a reward offered for her return and their arrest.
-Someone thought they were going to get an apartment. A student loan fell through and their roommate decided to move to Hawaii. Now they are couch surfing the dorms and hunting free food events....and they find a large community of people who have been doing this successfully for thirty years.
-Faculty stealing student research.
-Faculty having mutual restraining orders, concealed carry permits, and pulling guns on each other.
-Drunk ruminates wreaking havoc. Geico doesn't cover your car being destroyed by a drunk moose jumping on it while you're in class.
-Foxes steal your lunch, your money, your pot, and your phone.
-Missing classes gets you failed regardless of how smart you are.
-A scrappy group of student reporters bring down a group of city officials starting with drunk driving and ending with a sex trafficking ring.
-Unsolved murders.
-Was this a murder, a suicide, or an accidental shooting?
-Protests. Pick a reason. My favorite was when the coffee shop was closed.
-Big ass bonfires.
-Infectionous disease scares.
-Online homework is evil incarnate.
-The Internet slows from high speed to a crawl because everyone is doing their chemistry and calculus homework at the same time.
-A virus infects the homework system. Half the completed assignments claim they went the through. The instructors don't receive them.
-Bears. There's nothing like finding fresh bear sign when out doing an ecology lab and realizing everyone has been slowly backing away, leaving certain people as offerings.
-I could go on, but I realize that I have made my beloved university sound like some bizarre apocalyptic hellscape. Some of these things occurred before and after my time, but most of them where while I was there and keep repeating themselves. Because student loans lead to crime.
Throw Tim into this, and unlike Brentwood, have people act as if this is completely normal. Have him start questioning if he actually needs the uniform when other people are just as effective at ferreting out the problem without it. Give him the usual finals meltdown where he starts reeking of coffee and hallucinating because he hasn't slept, and people think that's socially acceptable. Let's see him be utterly confused because all of Batman's super villains are suddenly put in context and seem sane and reasonable. Have fun with it, just like real life college.
