She's a good British actress who apparently was desperate to be on GOT. Think of her more as Young!Maegi rather than Old!Maegi (because when Maegi of the books was young she was described as good-looking).
However whenever I watch that clip all I can think of is the other roles she's played in BBC adaptations of 19th Century novels. Most especially I think of her in this one:
that has to be the most evocative love triangle evar, cersei loves tywin, tywin loves jaime, jaime loves cersei. Their biggest disappointment in life is the lack of that love being reciprocated.
Liked how LF got Sansa and Varys got Tyrion, looking forward to when Tyrion and Sansa meet next Lol @sansa, so you are going to a land where you trust everyone
that is some dark humour there, coming from someone who really does not care
