During the second act, when you first enter your Hightown mansion Aveline will ask you to deal with a problem she has with the Templar Emmeric. During the conversation you will get a chance to question her about Emmeric's investigation. When you choose the question that asks her why she would not investigate it with the guard, she talks about the Gascard de Puis house raid, then finishes it by saying "Why can't he just build a boat like other old men." This is a reference to the television show NCIS and the main character Leeroy Jethro Gibbs, an old federal agent who builds boats in his basement.
