This story might be a little confusing for some, but the gist is Chris has been in the past for two and a half months without his memory. All he know is his name Chris Halliwell and he's been pulled to both the Bay Mirror and the Temp Agency, now he's inevitably been drawn to P3 and the manor.
So basically a lot of S6 never happened.
"I saw that guy again." Paige called as she walked into the manor, "I got a photo of him this time!"
Piper and Phoebe looked at her phone, "Oh I've seen him around the office…"
"I haven't seen him before." Piper mused, "Maybe he just needs the cash?"
There was knock at the door, Piper opened it, "Hello?"
"Um hi." The young man said nervously, "My name's Chris Halliwell," he paused at the look on the woman's face, "Mike at P3 said if I wanted a job I should come see you…"
When Piper didn't say anything Chris asked, "I do have the right address don't I? I've always sucked at getting places right."
"No, you have the right place." Piper said as she stared at him, "Come on in."
Chris walked in behind her and looked around confused; "Have I been here before?"
"No." Piper shook her head, "Why do you ask?"
"It feels like I have…you see I kinda lost my memory about a year ago I think, rather severe retrograde amnesia. All I know is my name and the fact I'm twenty-two."
"What about your family? Surely someone is missing you?"
"Well nobody came to the hospital." Chris shrugged, "So I guess I don't have anyone."
Paige and Phoebe walked in, "Piper you let our stalker in the house?"
Chris looked up, "Stalker?"
"Well you're always at the Temp agency or the Bay mirror."
"I work there." Chris reasoned, "I do what I can for extra cash."
"Girls," Piper said, "This is Chris, Chris Halliwell."
They all stared at him as Piper guided them into the kitchen.
"Did I grow a second head or something?" Chris joked nervously.
"Sorry." Phoebe said, "It's just…you look a lot like my sister Prue…and Piper."
"Oh lord…" Piper murmured, "He does."
Chris started to feel increasingly uncomfortable, "Um, Mrs Halliwell about that job?" he touched the island table and suddenly a rush of images flooded into his brain, as they stopped he lost his balance and fell to the ground.
"What happened?" Paige asked.
Chris tried to find the words but was cut off by Phoebe, "Chris what did you see?"
Chris looked up and pointed to the being floating in the air, "Him!"
Piper flicked her hands and the darklighter didn't blow up she said, "Alright, Paige get out of here!"
"I can't orb." She said ducking behind a table as an arrow came flying at her.
Then the darklighter's attention turned to the young man leaning against the wall, aiming the crossbow at him he frowned as Chris' body slumped forward; behind him Chris reappeared and looked around for something to use against the creature. Spying the letter opener and with a precision he didn't know he had he threw it at him and the darklighter burst into flames.
Chris' spirit returned to his body, "What the hell?" He muttered as he opened his eyes.
"I think it's safe to say he's one of us." Piper mused.
"One of what?" Chris asked hesitantly.
"Witches."
