My version of 'Buck is still Tommy's emergency contact':
The first thing Tommy notices waking up, apart from the pain, is Evan pacing in the room and ranting about "how he could dare to do something like that" and "how he hopes to never get a call like that again".
So Tommy dejectedly tells Buck that he will delete him as his emergency contact, only to be met by an outraged look and a "And find out through the LAPD grapevines?! Don't you dare Thomas Kinard. I might be terrified of getting calls of you in the hospital but I will come running every single time."
There's a few seconds of silence until Tommy answers with
"You better make me yours as well then."
"You still are."
"Good."
"Good."
Then they smile their Tommy/Evan smiles at each other and because they're allergic to communication they don't get back together at that moment but Buck can't stop fussing over Tommy since he's injured.
Somehow that results in Buck moving in and never leaving again.
