[What Sanji feels can't be described easily - for Richard to truly understand the torment that comes from watching a helpless boy knocking on death's door, Sanji would have to exchange one of his darkest memories in return.
That's not an option right now, though. They're preoccupied with the current memory and won't be escaping until it ends. At least the heat simmers down after the initial explosion. He's still angry, but in control now. Unfortunately that doesn't make watching any easier. His arm and fingers twitch, held tight against his side so he won't make any unnecessary motions - like reach out for a child who can't see him anyway - and eventually, Sanji shoves both hands into his pockets and stares mercilessly at the floor]
