Hospital visits (feat. Black).
Shiro gets away with visiting any time he damn pleased because he is The Captain of Atlas, Hero of Earth, Garrison’s Golden Boy etc etc. Also he’s really too busy to stick to the regular visiting hours, I guess.

Bonus:

When things get really really chaotic in the Garrisson and everyone- especially the Captain- are stressed out, Shiro sometimes disappears a little too long during breaks. The crew will draw a lot on which one of them will have to go to Kogane’s room and face his irritated glare as if the fetching personnel is the one personally responsible for the Captain’s exhaustion.
