As I was watching this episode, I couldn't help but think how emotional it must have been for two of the main characters involved to film. Seamus Dever (Kevin Ryan) and Juliana Dever (Jenny Ryan) are married in real life. As the story plays out, Kevin is trapped inside a burning building. Jenny is in labor with their first child in an ambulance outside. She refuses to leave until she knows what will happen to him. I'm sure it had to be intense for both actors, imagining their spouse in such a situation. The strong friendship between Ryan and Esposito is clearly shown as well.
