I know for sure that burt, carol and rachel are also in the fic. The plot is that kurt is already safe undeground but goes up to repair some tower and finds blaine holed up in there. The malfunction was because blaine spilled juice on the wires. Kurt takes blaine with him back under.
I think blaine has a boypussy too...and blaine is really scared at first but gets comfortable and he and kurt get together.
That's all I remember! Hope someone can help find this!
