L's wide eyes blink, a rarity. He cants his head, before choosing his words very carefully.

"To tell is a very conscious action," he replies softly. "My life is something the merest bit of information could forfeit, and my caution hasn't changed, here."

But his control has. There are shared dreams, magical occurrences, psychic Bonds and bizarre flukes that can coax things out of people. Light will learn in time, might regret any harsh sentiment he currently holds. Even so...

"Details of the case aren't known to most. Even Myr is only aware of the essentials; my profession. The general circumstances of what I was doing before I came through the mirror. He knows that I had a handler, that I helmed a task force, that there was a mass killer at large I disagreed with on a deep philosophical level."

He straightens slightly, turning away so that he can stare into a middle distance (or the wall, which would ultimately be a practical venture fruitful to their current goal.)

"He knows that you were my friend, and that I value our friendship."

He even knows that I am unwilling to give it up, knowing what I do.

Dying, how he had.
