The following paragraph is an excerpt from the NYT article:
Just don’t call him a dirtbag, Moss-Bachrach pleaded. “I get a little sensitive,” he said. “My feelings get hurt.” He’s made a specialty of stunted men — see also: his cringey musician in “Girls” — but he loves and respects them nonetheless, especially Richie. He’s “passionate, and loyal.”
Why was a comma used before and in the bold phrase?
