Aela is female btw. Whiteflanes claim is scum if its male vs female.
However, the fact he claimed that after all this time to make.it up and I pointed out Serana is female makes it more likely he is real and the split is different.
His reason for tje role is a bit silly but Aela was a huntress and tracker. However, she is more akin to a mafia scout than tracker but who cares
