He knocked on the door smiling happily at the Christmas decorations on Jackie Tyler's porch.
The door swung open and a blonde woman stood there ready to scold the intruder but quickly gasped at the man standing there.
"Oh my God, Garth is that you?" she asked beaming brightly.
"Hello Aunt Jackie." Garth said hugging her tightly.
"You must be freezing standin' out on the porch like that! Come in! Come in!"
Garth followed her orders and strolled into the hallway. "Is Rose coming?" He asked beaming brightly.
"Yes and she's bringing a friend." Jackie said pursing her lips at the thought of him.
"Is it the same one as last time?" Garth asked, still smiling.
"No, the Doctor won't be coming around anymore I'm afraid." She said sorrowfully. "But I'll explain that some other time. This one's an American fellow, like you! She met him on the train. A bad influence if you ask me."
Jackie continued to go on about the man Rose was bringing and Garth listened politely, smiling the whole time as she brought him hot chocolate from the kitchen. It wasn't until she mentioned his name did Garth interrupt.
"Wait, what was his name?" Garth asked looking up wide-eyed to his aunt.
"Sam I think. Sam…Winchester! That's right! But anyway-" and so Jackie continued while Garth sat there in shock at who his cozen was bringing to London for the holidays.
I love Garth. If I were a character from Supernatural it would be Garth. He is awesome. Also he isn't 'technically' their nephew. He worked a case once and pretended to be a distant relative to talk to Jackie about the Doctor.
