'Downton Abbey' season 5 spoilers: Is somebody in the estate saying goodbye in episode 7?

Isis the Labrador from Downton Abbey Wikia

Edith's (Laura Carmichael) sudden disappearance in the previous episode of "Downton Abbey" season 5 only paved the way for more drama that will be shown in the seventh episode of the hit PBS series. 

In this episode, Edith's plan to stay away from home falter after someone finds out about it. But since she has no other choice but to return home to her family, she has to think of the right way to keep her daughter Marigold away from their prying eyes so that no one will know that she gave birth to Michael Gregson's (Charles Edwards) child. 

The official synopsis for the upcoming episode reads: 

"Bates' train ticket returns to the spotlight. Isobel encounters a surprising obstacle to happiness. An arrival brings new hope, while departures bring both relief and sorrow." 

It means that this episode shows that Anna (Joanne Froggatt) and John (Brendan Coyle) Bates's situation improves after proving that the latter is not responsible for the murder of Alex Green (Nigel Harman) at the train station. However, it does not mean that the couple is finally safe from the police. 

But who among the characters of the show will depart in the episode, which will bring both joy and distress to the entire family? Could it be Tom Branson (Allen Leech), the current estate manager of Downton Abbey whose political views oppose that of the family? Or could it be any other character? 

The next installment of the high rating period series is the controversial episode that involves the show's dog, Isis. When the episode was aired in the U.K., a lot of people were concerned about the plot involving the Labrador retriever, as well as the reference of her name to the terrorist group. 

Also, Isobel (Penelope Wilton) starts to get closer to Lord Merton (Douglas Reith), but Lady Violet (Maggie Smith) will not approve of their relationship. 

"Downton Abbey" season 5 airs every Sunday in the U.S.
