User blog comment:Andrew Waltfeld/Story-line Plot up till Episode 16/@comment-10390252-20131002105140

My guess:

Episode 12 - Jaunedice part 2 - Jaune learns some life lessons and gets some character development, possibly by massaging Cardin's face with those knuckledusters built into his gloves;

Episode 13/14 - Either Blake or Yang/Ruby family focus chapter. Most probably Blake;

Episode 15 - Double-length episode, possibly a set-up of Volume-end cliff-hanger. I've got no idea what this may be about but one random guess: Team CRDL have had their heads handed to them by RWBY during a field exercise. A humiliated Cardin is approached by a shadowy individual who promises revenge and greatness in exchange for a simple favour. We know it's Roman but Cardin is too blinded by his own desires to wonder who this hooded guy might be (also some character moments firming up the various relationships and attitudes towards each other in and between RWBY and JNPR);

Episode 16 - Volume-end cliff-hanger double-length episode. Maybe we'll finally have Team RWBY meet Crimson and her two side-kicks. Episode ends with Crimson shrugging the girls off like they're paper dolls and powering up a big attack.
