Riggs and Miranda get all cuddly before the birth of their son. Riggs looks incredibly happy here, but we know that happiness will turn to sorrow soon.
Riggs and Murtaugh are taking advantage of some downtime by having a nice dinner. It's good to see them talking, but we're quite curious as to the subject of the conversation.
If we didn't know better we'd think Riggs might have had a little too much to drink, but it looks like he just got caught on the wrong end of a happy partygoer. Murtaugh seems to have the situation under control.
Riggs is probably showing off his skills to Murtaugh who doesn't seem to be that interested. Put him in a bowling alley, and he'd feel much more at home.
