Destiny Rumancek says the story Lynda Rumancek told "sounds so much better in Romanian." However, as gypsies (Roma), they speak Romania (a form of Sanskrit), not Romanian (of Latin origin, close to Italian and Spanish). Throughout the series they speak words and phrases in Romani and, in the last episode, Romanian.
At around 27 mins of the episode, Roman & Norman walk out of the abandoned church, & you can see in the reflection of their red car movement of the behind-the-scenes crew.
