Odds are it is in her HEAD reflog.  You can look for it with
`git log -g`.  If you know some part of the commit message you
may be able to filter it down with `git log -g --grep=X` or part
of the change with `git log -g -SX`.

A coworker just did something like that today and lost his change;
looking in the HEAD reflog and cherry-picking the commit recovered
it quite easily.
