"Dynamite"

Within Jesse's mind, Jesse finds an In-Universe music video featuring the (still live-action) Darling and Trench rocking it out to a slightly reworked version of "Dyna-mite" by the UK glam rock band Mud, even featuring a title caption and supposedly being produced by "Federal Bureau of Control Records." It's so outrageously silly and complimenting of Jesse that she has to comment on how weird it is... then remembers that this is taking place inside her own mind, so really she's the weirdo who came up with it.
