Yep. For all intents and purposes, Monarch is a better man. He cares about his gf, he cares about the people under him and wants to be the best he can be (whatever that is that episode). Even Dr. Girlfriend with her whole "You don't fire with fire, but with water" stuff kinda reflects that. If Dr. Venture actually started instigating, he'd totally be actually arching Monarch.
I was thinking that too. When your arch-villain is more successful at their 'job' and in life...what's the point of arching? Time for Dr. Killinger to return!
And that I do like. Also, 21's new role is awesome. Great shot of him running toward the e-den with the cocoon approaching over it.
