Like you say, this time the Switcher was kind of obvious. Though for me, it was because there are 4 guest characters with 3 of them having appeared as the Switcher in prior episodes.

And speaking of the obvious suspects.

Sentai-lert

Our villain of the week his time is played by Kasumi Suzuki, who was previously major villain Lije (and her unnamed heroic clone) in Bakuryuu Sentai Abaranger as a child actress, and Jyuka’s friend who unleashed a Worm in the high school two-parter from Kabuto.

Also, thoughts on the episode ending: The university the graduates go to being round the corner is an obvious cop-out because they aren’t going to jettison two of the heroes halfway through the series (unless the actors had to leave and/or were fired)
