Earlier in the day, the new Greenie(Thomas, though they don't know his name yet because Thomas can't remember his name just yet) had come up in the box and into the glade with the note of him being the last one. The gladers are around the bonfire, drinking and partying as they do with their own brewed, piss-tasting alcohol.

Newt notices Thomas(you) sitting by a log seat, just looking lost and confused, kind of sad(?) too

"Hey, Greenie? You alright there, mate?"

Newt asks Thomas, sitting down next to him and ignoring the chants of the other gladers behind them
