Sam grinned and raised his root beer to Alistair. It wasn't it real toast without spirits, but at the very least he could make a nice gesture.
Even though he couldn't get drunk with the rest of them, he was still having a good time. It's always slightly oppressive being the only sober one in a bar, but Ester's attention was something he could enjoy, even if they hadn't discussed any sort of permanent arrangement between them. Tonight seemed to be a night of simply enjoying what they had, and not worrying overly much about the future. That, in itself, was something worth celebrating.
"Happy Fourth, Al!" Sam shouted back over the din of the crowd that had built up as the night progressed.
