"I'll rest if you do," Strange simply responds. Because you bet he heard Pod 153. Strange...doesn't entirely know what 'system maintenance' and 'full data overhaul' mean but he's got a good idea about what Pod 153 means by semi-uncontrolled state. Something messed with 9S's emotions and Pod 153 wants him to take a break, calm down, and rest as well.

He's also noticed that he didn't get that please. Dammit, kid. Still, 9S is obviously grumpy about something so might as well at least attempt a conversation.

"Do you wish to talk about this 'semi-uncontrolled state'?"
