Although it wasn't my favorite episode, I rated it high b/c I did enjoy it. I like Nelly Furtado's music, but I didn't think much of her acting in this episode. The scene between her Ava and Stella was awkward and not really believable. Ms. Furtado was definitely not up to being opposite Melina.
The secret society arc was enjoyable, but felt a little off. The interaction between Mac and Reed made the storyline for me while being subtle and natural.
My favorite part of the episode- Adam. This episode showed that there's more to Adam than just being a quirky lab rat, and I'm hoping TPTB explore that more.
