Ron Weasley
Ron had a little too much to drink at/after the fair and forgot to set a magical alarm on Sunday night. He will wake up in a panic Monday morning because he's late and will rush through his showering / dressing / apparating to work routine. Except, instead of apparating to the forest, he'll go straight to the Ministry. Although Redux!Ron has never been to the Auror Office, he will find his way from the Atrium effortlessly, and only realise his mistake when he stops at 'his' cubicle and there's someone else already sitting there. He'll head to his actual job, slightly unsettled. It won't be until after work, when he gets undressed for bed, that he sees old-looking scars on his arms that will be gone by Tuesday morning.
Other symptoms will come in sporadic bursts that last anywhere from a few minutes to a few hours: a deep affection/love for Hermione, a concern over Harry's location and well-being, dreams of a giant chess set, dreams of pulling Harry from a lake, waking dreams (aka memories) of the battle, extreme frustration with Hermione, forgetting who Evan & Daisy are, calling Fred 'George', asking after the health of his nieces and nephews by name, confusion over where all his money / nice things have gone.
