Three details that help show Owen's feelings without saying them directly are: closing his eyes, feeling a bulge in the back of his throat, and having wet palms.

These details suggest that Owen may be feeling overwhelmed, anxious, or emotional. Closing his eyes could indicate a desire to shut out his surroundings and focus inwardly. Feeling a bulge in the back of his throat could suggest a lump forming due to suppressed emotions or the inability to speak. And having wet palms could indicate nervousness or agitation. Together, these physical reactions hint at Owen's inner turmoil or heightened emotional state.
