text: During one of James' visits, where he takes Mikey and Julie out to the movies, sneaking them in and getting them popcorn for free, he spends the day with them and this makes Mikey realize that he may have been too hard on his sister. Later, when Julie decides she doesn't need Mikey and wants to strike out on her own, she is inspired to walk unsupported. Mollie sees this and showers Julie with affection for her accomplishment, the happiness is short lived however, as James is not there to share the moment. James returns home to talk to Mollie and Mikey accomplishes going to the bathroom on his own, which is a celebration both of them share with him. James is due to go flying and with a massive storm building in the area, Mollie gets worried and leaves Mikey and Julie in Stuart's care. While she is gone, a robber sneaks into the apartment and Stuart scares him out with his gun. Forgetting that Mikey and Julie are in the apartment, Stuart gives chase, leaving the stove on, which then catches some paper he left on the stove on fire that begins to spread quickly through the apartment. Thinking quickly and calmly, Mikey manages to push Julie out of harm's way.
  Meanwhile, James and Mollie returning home from her stopping him from taking off during the storm return to intervene and subdue the burglar that Stuart is chasing. Momentarily panicked seeing fire in the apartment, Mollie and James are relieved as Mikey exits the elevator with Julie in tow. James runs to the apartment and puts out the fire before any major damage is caused and the day is saved. Later, at a barbecue with James, Mollie, Rona, Stuart and Mollie's parents, Julie and Mikey have a conversation on how strange the adults are, and how much they are needed in their lives. Julie agrees and the two walk off together hand in hand.
