Sock Puppets and European History - S1.E20

Carmilla tells Laura her story of becoming and "living" as a vampire, with Laura suddenly deciding to pep it up by playing along with sock puppets. Which, at first, works delightfully when it's all about adventures centuries ago. Alas, it ends sadly when Carmilla's real love was struck by tragedy, and she began to disobey her "mother", who Laura already met.
