Judging by they way they stare, the fruit is fascinating to Phalanx. The way Delta finds a place to sit is also fascinating. Watching him move and eat is fascinating.

And it gives Phalanx a lot to work with. They're remembering, slowly, as they watch their new friend. They take a seat when instructed, moving just like the other man had. They also follow his cue in taking a bite of fruit.

Their careful following and mimicking is interrupted when the taste of the fruit actually registers, however. Right as they seem like they're about to respond to Delta's advice, a surprised blink cuts it off.

Staring at the fruit in their hand. "It's... not right?"
