Beyond's eyes narrow at L. Those memories of his last stay here rushing back to him. And the final battle back in their homeworld. How did he lose to this man, knowing everything Mello told him? He knew the details of his loss, he should have had the upper hand when he went back. And yet, he still played right into this detective's hand, as if he knew nothing of it at all.

He still lost, to Misora and L simultaneously. Despite everything, everything that happened in Hadriel before.

"So you've come back after all, L." His voice is bitter, sharp. A blend of mixed feelings from having killed the man before him, in rage and euphoria, and having himself be defeated by the man before him.

And he turns his gaze to the pool before him, if only for a moment, to ponder L's query. But his eyes do return to L just as quickly, as though unwilling to keep his eyes off the detective.

"Now, why is that? Are you afraid, L? To test it yourself. You seem just as cowardly as you did the day of our battle. I suppose that comes as no surprise."

Still, that water theory should have an answer soon enough, shouldn't it? Just like L to observe from afar, as he knew of the man back in his homeworld.
