'Downton Abbey' season 6 spoilers: Mr. Green's death to finally be resolved

One of the biggest mysteries in "Downton Abbey" is the mysterious death of Alex Green (Nigel Harman). Mr. Green was said to have been killed by a bus after he tripped. However, the circumstances of his death have remained a mystery, particularly after he raped Anna (Joanne Froggatt). According to a new report, this mystery will finally be resolved in season 6. 

Speaking to Deadline, Froggatt stated, "We do see the mystery behind Mr. Green's death resolved. Obviously how it's resolved I can't tell you, or whether it's good or bad for the Bates I can't tell you, but it's resolved." 

She continued to explain that viewers will be able to get to the bottom of what exactly happened to Green and who may have killed him, and that there will still be lots of drama between Anna and her husband John Bates (Brendan Coyle) in season 6.

Froggatt then concluded by stating that while there is happiness for Anna and John, this happiness is never easily attained. This theme will carry over until the series finale. 

According to a report from IBTimes, this might mean that John Bates will be hanged even though he may not have been the one who killed Green. It is likely that the truth will come out only after his death, when Anna is forced to investigate things further and discover what truly happened. 

This sentiment was shared by series creator Julian Fellowes back in March when he stated that there are people who are just unlucky in life and that this may be the case for Anna and John, although the key difference between their situation and that of Edith (Laura Carmichael) is that they have their love for each other to keep them going.

"Downton Abbey" season 6 premieres in the U.S. on Jan. 3, 2016.
