When Elijah turns to Marcel for help in tracking down a vital piece of information, he is forced to remember a time long ago when they were on better terms. Meanwhile, Davina and Kaleb (recurring guest star Daniel Sharman) find themselves in a dangerous situation when unexpected visitors show up and crash their dinner. Finally, Klaus grows suspicious after a meeting with Cassie (recurring guest star Natalie Dreyfuss – The Secret Life of the American Teenager) doesn't go as he had planned.
