Ash Lynx is always calculating the exit
His intelligence is inseparable from the need to read danger before anybody else in the room does.

Coverage: Premise and early character setup
Competence is not comfort
Ash’s ability to understand an unfamiliar situation quickly can make him look in control even when the situation is coercive. Banana Fish repeatedly puts a young person’s extraordinary competence beside circumstances he did not freely choose.
The difference matters. A character who can win an argument, recognize a weapon or anticipate an opponent is not therefore safe. His skill may be a record of how often safety has been unavailable.
Watch the room around him
Ash becomes easier to read when you follow entrances, lines of sight and changes in who is listening. A conversation can become dangerous before anybody raises a voice. His attention gives the reader clues about a threat that another character may not yet understand.
The quiet scenes matter because they change the use of that attention. When Eiji is present, Ash can briefly be seen as somebody other than an asset, an opponent or a problem to control. The story does not need to make him less intelligent for that possibility to matter.
The cost of being the one with the answer
A group’s reliance on Ash can turn his competence into another obligation. He is expected to anticipate the move that keeps everyone alive. Notice when a scene lets him receive help without first making him prove that he deserves it.
This is a premise-level reading of the character. Later plot events make the distinction between capability and freedom more painful; they are not needed to see it operating in the opening.
