Remembrance (джен)

I posted a prompt on Norsekink and then the plot bunnies ran rampant and I ended up filling it myself.
Tony Stark invents a weapon designed to incapacitate Loki, but it doesn't work how they expected it too. Loki loses all his memories, he can't speak, he doesn't know who anyone is, he can't even feed himself so The Avengers have to look after him. Then aliens invade earth and it all goes a little bit crazy.
