Even without foresight, it's obvious after the first few notes. He's buying time. Or just being irritating as fuck. Irregardless, Liam is brooding somewhere stupid, again, probably some nondescript closet in Kate's Land Of Bullshit and Cats. Yet the price of skipping is asphyxiation or stabbing himself or throwing himself down a flight of stairs, which is even stupider. Following the note trail it is.

So when Liam finally has his requested level of time wasted doing absolutely nothing, the requested visitor appears. And drops all the notes on his face.

"If you're bored, go out and get arrested for misdemeanors like normal people."
