For the past episodes, I think it's all about Tamsin and her mysterious motives. It's just hard to decipher this girl. First, she can't wait to lock Bo down. Now, she's helping her and can't seem to get off her side.
Bo's practicing for The Dawning which makes her neglect her girlfriend unintentionally. When she was about to get some rest and meet up with Lauren afterwards for her acceptance speech, she was snagged by Tamsin. She said that the people around her were all lying and that she doesn't have a chance with The Dawning.
But what's funny, after Bo and Tamsin's weird, long adventure, Tamsin ended up kissing Bo. And that kiss didn't show chi but it showed a genuine kiss from the Valkyrie. Oh Tamsin, why do you have to play with our minds?
And Lauren? Oh, she didn't attend her event. She was alone at home drunk still in her evening dress waiting hopelessly for her lover to come. But instead of Bo, someone came to fetch her. It was a man, also I scientist I presume.
