The Orville event only had Seth scheduled to mingle with the crowd, but a few other cast members ended up sneaking in, as well.
Penny Johnson Jerald plays Dr. Claire Finn on the show and she ended up coming for a photo op as we were waiting for our picture. As she wanted to cut before us in line, we said she could if she took a picture with us. :) We're so tricky. It turns out she was super nice anyway and was interacting with a bunch of people. Really sweet lady!
