Temporally Displaced Twins: Not So Dead Fred

Fred Weasley finds himself in his 16 year old body, first assuming this is nothing more than a walking daydream he and George had been working on... but things are a little too real. He can taste and feel things he shouldn't be able to, feel things that shouldn't be possible. It takes a moment for the reality to set in that he has some how been sent back to his younger self, long before the war truly starts.How will Fred handle being alone in the past, could he ever explain what's coming to his twin? Did he even want to?What's worse, Snape keeps staring at the time displaced wizard, unnerving the lad beyond anything else. It wasn't fun having Dumbledore's murderer staring him down like this.
