L turned on his heel and stuck a hand out for Zexion to shake. "It's very nice to meet you, Ian," he said as politely as he could. As far as he could tell, Zexion was hiding nothing from him, and there was no reason for L to try looking for reasons why he would try. They would get to know each other well soon enough.

"Please be sure to tell me when you leave, however. If I need you and you're not there, then that could be an issue. Otherwise, you are free to come and go as you please." L wasn't going to limit him relentlessly: he would only give more incentive for "Ian" to never come back. He had to show that he was flexible...which he was.

There were no crimes to research or catch word of, only cleaning. That wasn't complex at all.
