"I-I know, but." She started to protest against Timea lecturing her on the 'everyone here is a stranger' aspect, that situation a bit clearer to the girl than Timea gave her credit for. When the idea of getting to know each other came up the girl seemed to ponder it for a bit, before slowly nodding her head with increasing vigor. "Y-ya, that's true." She seemed to agree, the faintest trace of a smile coming to her face. "My name's Hillary." she replied almost immediately after Timea did.
The hand taking was not quite as instant, but after a bit of coaxing Hillary would move back closer to Timea and go to make contact with Timea. This would have the unexpected result of Hillary, and even the ground that was under her converting to a material nearly identical to Timea's skin. The change overall would only take a couple seconds to fully complete, starting from the contact point with Timea and spreading from there.
In addition to the change, the section that was once sand almost immediately sank into the ground by a good few inches, flinging up a good jet of sand that had been underneath the once sand mound. Through the dust, Timea would see Hillary had changed appearance somewhat, even when disregarding the 'not being made of sand' part. Largely, her hair which had been straight and long before had now become more closer to dreadlocks, and she now appeared to now have a full set of legs instead of the partial calves she'd had before.
Needless to say, Hillary was freaked out over the change, and would fall backwards in surprise with a yelp.
