"A lot of things", Li replies curtly. "If you've not been drinking, then have you perhaps hit your head badly earlier today? There's some uncertainty to your steps and your gaze is off."

Instead, it appears the Commander is leading him towards the Central Hospital... though there should be a more direct route there too.
