With Peach's death I feel the show has just lost a big part of itself. The show needs someone from with the inner circle (friends or family) to weed out these predators. Also, none of Beck's other friends are smart enough to detect Joe's pervy nature...so its now up to the Police to close the net on him.
Not sure if I was right, but did Peaches & Raj use sex toys because they are both gay (knowingly)? and it was all a ruse to rape Beck?
Paco's mom surely will have a role to play in the final few episodes. I was actually surprised to see her featured. I wonder if she knows Joe's true nature having lived next to him for so long. Blackmail for end of season, I hope.
