Thunderbirds wouldn't be complete without the literal brains of the outfit, er, Brains. He has a slightly updated look for the new series, with smaller glasses and less outlandish clothes, but remains recognisably the technical guru of Tracy Island. Hopefully, he'll still have his mild stutter. It's also exciting to note that the room where Brains is standing in the trailer has the pictures of the Tracy brothers and Kayo up on the wall. In the original series, the pictures can change at the press of a button when visitors come to the island, hiding the portraits with the heroes in uniform and replacing them with shots of the same people in casual clothes. It would be a great homage to see that same feature in the new series, too. One last thing about this room - it's the room where wall sections swivel round, allowing the Tracy brothers to quickly board their Thunderbird vehicles. It would be even nicer to see updated versions for those sequences! And, since Kayo's picture is up on the wall, expect to see her in as many adventures as the boys.
