Whenever people on the island disappeared - which seemed like quite often these days - Jo was always glad of the people that were still here. Johnny was one of them and now he'd disappeared too. Once she'd got over her initial disbelief Jo had gone to the TARDIS via her room to pick up the key. Despite waking up with it a few months ago she'd never used it: the TARDIS didn't go anywhere so there hadn't been any reason to go in it. Now, though, she let herself in, took one look at the inside and leaned heavily against the door.
"I want to go home." The inside wasn't the white walls that she remembered and the Doctor - the white haired one from home - wasn't in the console room to rescue her either. She put a hand to her mouth, which didn't do anything to stop her eyes from filling with tears, and ran out of the console room further into the TARDIS. Not far down the corridor she came across a bedroom. Not caring whose it was, or had been, she flung herself onto the bed and cried into the pillow.
Sometime later she lay on her back listening to nothing much and tried to think about the good times she'd had with Johnny and not what might have been, had he still been here. Eventually the quiet and the lying down with her eyes closed lulled her off to sleep and she dreamt of home.
She assumed it was morning when she woke up simply because she woke up, but it was hard to tell. Not being quite able to know what to do with herself, she stayed where she was, until the lack of noise of people got to her. For all she knew everyone else on the island could have vanished in the night. Once she thought about it, the thought wouldn't leave her and she ran back outside, worried and scared.
There were people around, which was a big relief. As she ambled back to the Compound in the morning sunshine she considered what to do now. This was just an ordinary day, despite what had happened the day before, so perhaps she should just treat it like one. She remembered
the present that had turned up this year for her in the lab. She'd had lots of fun investigating all the different parts of it and had been excited about going out and finding out what was in soil. She just hadn't got round to doing any research, as that involved reading books written in a way guaranteed to put you to sleep. There had always been more exciting things to do.
But now, she was determined to be a scientist and that involved some boring stuff. Since she was after something to distract her, she decided to spend some time on it.
