House

Jack couldn't just leave well enough alone. When he had free time, he found himself haunting the hospital, driving past Greg's building, spying on him as he got coffee. He even lo-jacked his bike.

But actually talk to the man? That wasn't in the plan.

He was actually in the hallway outside the clinic when his phone rang. He stopped to look at it, but it was just his boss so he swiped the call away.
