Brennan’s team has also been evolving, with Angela (Michaela Conlin) and Hodgins (TJ Thyne) getting married in “The Witch In The Wardrobe.” Hanson explained, “We'd already done them getting married in a season finale. And I thought, let's just pop it in when no one's expecting it, that these two will get back together. The scene where they talk about how they broke up has existed since they broke up. It wasn't in a jail cell, I didn't know where it would happen, but that scene has existed and has been written for a long time where they realized how they let each other go. And it just felt like the right time to get them back together. I do sometimes think of the Hodgela, the Hodgins/Angela relationship as a— like a steam valve. It lets off some pressure, but it's not small beer. It's its own story and we wanted to go into season six … with them married. That'll be fun.”
Angela’s father (Billy Gibbons of ZZ Top) will make a guest appearance in the finale. Asked how Gibbons’ involvement in the show came about, Hanson replied, “I always knew that Angela Montenegro was not Angela's real name, and I always knew that she had a rock star dad. Because it's just funny to me that the guys I idolized as a kid are all now grandfathers ... I didn't know who it would be. And when you start going through the list of rock stars who are instantly recognizable … it's a very, very small group of people."
"I made a list of about five people who I wouldn't have to explain who they were. Now, not everybody knows Billy Gibbons' name, but they would call him ZZ Top with that beard — and he responded. He was on that very short list and he responded. This man was Jimi Hendrix's favorite guitar player when he was 19 years old. He's an amazing, amazing person. So I selfishly used the fact that I had a TV series to meet one of my idols, and then he turned out to be a really interesting actor. It's still to me one of the great thrills of the show to have Billy Gibbons appear from time-to-time on our show when he's not touring the world being a huge rock star.”
