The darach is Cora.

in visionary gerard says the druids can SHAPE SHIFT whether shape shifting includes shifting to the looks of another person or not we do not know for sure. darach is a druid.

cora didnt know derek was alive. how couldnt she? it was in the news.

cora was "unaccounted for" for 6 years.

even peter doesnt trust her.

the flashback episode, on the school bus, was probably made non-linear to make cora less conspicuous.... making her actions again "unaccounted for". and they actually left a very important clue that episode, it showed that peter didnt trust her. and peter is usually right with his suspicions......

and doesnt anyone find it suspicious on VISIONARY that CORA didnt know how and why dereks eyes turned blue? shes dereks sister and should have been around during that time.

although she said "how do you know this" to peter was probably just her trying to justify why she doesnt know.

also cora felt stiles knew something was off after peters story. if she was the darach then she would be uneasy with the facial expression of stiles. maybe in her mind, stiles figured her out....

also in the scene where peter and cora were in the vets parking lot, she didnt really mind the building made mostly of mountain ash.

given this info, the darach could be a being that shapeshifted into cora/werewolf.
