Although Chauncey has been working frequently during the pandemic; with bigger roles often with recognizable stars - Brendan's friendship with Thomas Ian Nicholas and Aaron Schwartz helped him nab a role in Adverse. This was just recently released in cinemas.
He probably didn't have any lines, so it's not a career pursuit like Chauncey...but to add insult to injury; Brendan got Luna a role too, so they undoubtedly became closer and had a chance to socialize.
I bet Chauncey is really frustrated by these events, hopefully he gets a role soon that overshadows this?
