Last Remnant art or fic. For art would love to see either a Rush-comes-back scene of an interpretation of of a possible alternate remnant form for Rush. (You have to wonder what he looks like under that mitra body...)
Fic would have to be Rush/David h/c to do with the aftermath of a battle where Dave used Ex machina/Gae Bolg. Maybe Rush manages to do something to help with his power, maybe he's just there to provide comfort, your choice.
