You ever notice the amount of Buddie scenes where you just ask yourself why are you guys hanging out right now.
For example that scene where Eddie is packing for El Paso and Buck is there playing with a toy dinosaur.
I know it's for exposition but like they rarely have a goal when they hang out. It's pretty much just proximity hang outs. Like there is no shared hobby, concert, bar, nor activity that doesn't include exposition.
Like Eddie and Tommy hung out to watch fights and play basketball. Maddie and dispatch did karaoke nights. When they were still friends Maddie and Chim hung out they had hang outs like karaoke too. Athena and Hen are hanging out at a bar. The girls have wine night. Buck hanging out at a bar with Ravi.
That's how friend hang outs work they make plans picking a setting and an activity.
When it is just Buck and Eddie they only seem to hang out when they are going to talk about something and deal with how their life is going. Maybe with a beer or two. Buck just goes to Eddie's house all the time to just plop on the couch. Other than that it's a hang out with Chris like the dinners, child activities, and baking. These two like being next to each other for no reason. They always will have each other's back when the other one needs it.
