Derek is trapped by a wall, how will he overcome it?

Character Bios:

Derek Roxen: Derek is the idiot of the group, he is always trying to overcome challenges by doing stupid things, such as using a grappling hook to get over an invisible wall, or blow up a building to launch himself into space. The day he dies will be the biggest step for humanity since the moon landings, that is IF they were real.

Richard Roxen: Richard is the mindless drone of the trio, ironically also being the most normal. He gets out of trouble in simple and mindless ways, such as walking in air to cross a sinkhole, or opening a door with an activated lock.....somehow. He also seems to be the smartest of them --- to sum it up, he is a genius idiot.

Josh Roxen: The Big Bad Bully of the brothers, he is always getting into fights with Derek, and always tries to provoke Richard, only to be frustrated from the mindless drone of a brother he has. The cops are always hot on his tail, which is why he remains hidden with his brothers.
