Sooner rather than later, they’d have to find out why the mare tagged along.  Was she chasing Dale?  It seemed obvious that the safest plan would be to keep the two apart, yet it would probably take forever to learn Dale’s language, which meant that they’d almost have to use Dale as an intermediary—he could ask the questions and then they could work at translating the answers.  It would be an arduous process, but there really wasn’t a better option that she could think of.  Maybe Twilight would have some idea, or even Cheerilee.
