The Doctor stayed with Sarah Jane throughout the night, whilst Amy slept in the guest room. Come morning the Doctor had disappeared, Luke found him trying to work the un-plugged-in kettle.
"Here." Luke offered, "Allow me."
Whilst Luke made breakfast for four, the Doctor pondered on something that had been nagging in the back of his mind. "How come you didn't phone?"
"Huh?" Asked Luke, looking over his shoulder whilst spreading butter on toast.
"You didn't contact me. Why not?"
Luke brought a plate piled high with toast and set it between them, "We didn't know how. Short of creating a national crisis, we didn't know how." He explained.
"Couldn't you just phone?" The Doctor mumbled through buttered toast, wondering where the custard was.
"You have a phone?" Said Luke, unconvinced.
"Yeah! Keeping up with the times, that's me! It's a Blueberry 'n' all!"
"You mean Blackberry." Luke corrected, reaching for seconds.
"Naah, Blueberry. Its the better version... The... newer one."
Luke tilted his head. "How new?"
The Doctor smiled as he raided Sarah Jane's cupboards, "Uh, bluuh," He wondered. Um... maybe... 2013... 2014... or..." He glanced over at Luke. Wow that boy took after his mother, the Doctor couldn't withstand her glare either. "2016."
Much to his surprise, Luke laughed. It was an odd sound, decidedly feminine. Luke wasn't even moving his lips. "How..." The Doctor started, then realised.
"Amelia! Come," He beckoned, "Eat, laugh. No wait, you're doing that already!"
The laughing stopped, and for the second time in two days someone slapped his head.
"Hey!"
