A possibility struck Alex when he took in all the variables surrounding the situation.
"Come," he said, quickly walking back out of the dead end.
Pearl wasn't sure what was going on, so he simply followed Alex. Alex walked back those two turns and stopped, not moving any further.
"What's wrong?" Pearl asked.
"I don't know," Alex answered. "But I'm going to find out. Hopefully." He just had to wait. The time he waited for now was the same time he was sure it had taken between him leaving the fountain and the two women getting there.
Once he waited for that amount, he ran back.
Pearl followed him, clueless as to what was happening. They took the two left turns and arrived back where the Fountain had been, where it hadn't been last time.
When they arrived, they were both flabbergasted to see that where there had been a fountain before and then nothing, now there was a massive tree there.
