The Fireside Chats with Brennan & Friends are two live-streamed bonus content episodes released before the finale for Dimension 20 LIVE featuring the main cast and Mike Trapp. They talked about the upcoming finale, various other seasons, and answered fan questions from the Twitch chat.
Due to the COVID-19 pandemic and social distancing as part of the nationwide quarantine, filming for the finale of Dimension 20 LIVE was moved out of the Dome and onto a virtual platform. In order to prepare the necessary technical preparations, the finale was postponed for two weeks. In its place, the cast gathered for the weekly stream time on Twitch to answer fan questions and talk about the show in "fireside chats" which would later evolve into the talk-back streams of Adventuring Party.
