Oh, for goodness' sake, people! Ari's "nanny" is called Mimi. Bini has two sisters on the show, and they're called Wish and Mimi. Sister Mimi looks NOTHING like nanny Mimi.
Ari did all but come straight out and ask Leandro to take her back. She was ALL over him, even though he was trying to be tactful. He has more common sense. He said he'd like to come back and visit "you two" but Ari had nothing but eyes for Leandro. She's looking for any excuse to leave Ethiopia and return to Leandro, and made it well known to Bini & the camera.
