It is noticeable, especially when you're as used to choosing the optimal place to stand as Akechi is. But then, it's also something he remembers Ren doing—real Ren, with his infuriating gift for going unnoticed

—and in his mind's eye he sees him for the first time, not Ren but Joker, surveying Madarame's ridiculous palace from its low roof, silhouetted in the blaze of the floodlights, and a bitter shiver goes right through him—

Stopping to get ahold of himself, he turns back to not-Ren, tempted to lean on the board. What is there someone so free with themself could be holding in reserve? Who would come into such a place and hold so little back?

"Mm. You know, the fact you mix up concern and panic is the most interesting thing about you so far." Interesting. Sure.
