The other's story
When they arrived at the Tyler Manor Jackie came out to greet them, seeing the Doctor and Susan she shot a strange glance towards them.
"Most people wouldn't take their new girlfriend to their old girlfriend's home. "
"Oh… but Susan's not my girlfriend. She's family."
"How?"
"I'm his great-great-granddaughter."
Jackie's jaw practically dropped.
"How old are you?" she asked, turning to the Doctor.
"Erm… about 900 years." He said, quickly stepping back before she could slap him. However, Jackie didn't do any attempts to slap him. Simply leading them inside and served a cup of tea.
"Okay… I'm sorry but I still have to get used to the fact that my daughter's practically dating a 900 year old alien who has a great-great-granddaughter just a few years younger than her."
"Well… actually I won't be born until the 27th May 2163."
For a moment Jackie, again, looked completely lost. Then she let out a small laugh.
"Oh… of course. Time travel. I forgot. Don't know how I could."
"Me neither. We were on our way to the sixties to visit some old friends called Ian and Barbara who used to travel with me and Susan."
"My grandma that is. I'm named after her. She was his granddaughter but you probably figured that out."
"Anyway, we sort of crashed here instead. Not that I mind." the last words he spoke while looking directly at Rose. In the same Pete Tyler came in with little Jason Tyler. Seeing the visitors he smiled and invited them to dinner without hesitation.
"Damn." The Doctor mumbled. "Domestic again. I'll never escape that." But the wide grin he shot Rose clearly showed her that he didn't really mind. When they'd finished eating a storm was coming up so the Doctor and Susan couldn't get back to the TARDIS.
"Why don't you just stay here?"
"Jackie, we only have one guest bedroom. Someone decided to use the other as a storeroom."
"It's okay. The Doctor will share with me."
With the sleeping arrangements settled they went to bed. Rose and the Doctor snuggling together.
