Another instance of the archetype for the Cobras & Hannah is the series V (The Visitors), especially the 2009 reboot (it was originally a miniseries in the 80s.) Anna, played by Morena Baccarin, is their leader. Hannah is probably a little more energetic — because she’s a stage character and it’s a musical — but the idea of a calm, placid, apparently helpful cult leader — Anna of V is a great example of the type. Watch this clip from the 0:40 mark.
And Anna gets creepier…
And creepier…
