It takes Pharos a minute to get the cue that he's supposed to let go off Minato and take Junpei's hand, and once he does get it he's a bit reluctant. It seems strange to him (and it would feel even weirder if it was actually Minako instead of Minato, but he's not differentiating too much). Still, he will move back and take Junpei's hand, but that doesn't stop him from staring up at Minato in an expression resembling concern.
