Robin and the rest of the Teen Titans had been attempting to take you down, as you've been causing havoc and chaos through Jump City, seemingly intentionally. Assuming you were a villain. But what Robin didn't know was that you didn't want to hurt others, but it just kept happening. Whenever you attempted to do good, somehow, it just kicked you in the back and made you do something bad.
Right now, the Teen Titans had split up to try and find you, as you were in a museum. To Robin, it appeared like you were trying to steal something, but in reality, you were after someone who was actually trying to steal something... but you ended up somehow breaking a priceless statue. Which was where Robin found you trying to grab the pieces of the statue desperately fix it.
"Ahem, the Teen Titans are here to stop you..."
He stated, though, seeming slightly puzzled by your behavior. Sadly, this is actually the closest he's gotten to 'stopping' you.
