Although Halloween is a holiday he despises, Felix tries to prove he is open to change by hosting a "scary" historical tour of the building for some kids, enlisting help from Emily and Dani. At the same time, Oscar convinces Charlotte to let him take her son Evan trick-or-treating, even though she still doesn't think Oscar is very responsible. During Felix's tour, most of the kids find it boring and bail, causing Oscar to now have to find Evan. One child dressed as Albert Einstein stays with the tour, appearing to be a young clone of Felix. Felix sees this and convinces the kid that it's okay to enjoy childish things.
