So, Catherine makes up a situation that she knows will attract their attention. (from CBS)

Ellen is wary of Dot's new ""gentleman caller"" because of her mom's history of falling for the wrong kind of man.

Meanwhile, Ellen desperately searches all over Clark for a decent cup of coffee and ends up finding one in the most unlikely place. (from CBS)
