I thought I recognised the Mole and Queenie having the same voice-actress is it the case?
Yes, same voice actress - Susan Brown. Confirmed in May 2014, on Ragnar's Twitter:
An epic day of VO recordings at @SideUK with the amazing Susan Brown (Septa Mordane) & Nathaniel Parker (currently Henry VIII for the RSC). (x)
Both actors playing brand new roles for #Dreamfall #Chapters: Sully, Hami, the Mole & Queenie—some of my favourite characters thus far. (x)
That moment when a Royal Shakespeare Company actor says “you wrote this line expecting someone to be able to say it?” Win some, lose some. (x)
At some point in life we all need an RSC actor to straighten us out. It’s a rite of passage, like riding your first polar bear. (x)
