You could tell she had those zingers locked and loaded and was just waiting for the right time to drop each of them.
You could also see her when she decided to chamber the round. Where her stern disapproval face had brief flickers of delight as she decided she was going to use one when she had her next chance to speak.
I think her campaign is what an actual campaign is supposed to look like, it just looks incredible when you compare it to the dumpster fire that is Trumps campaign.
I still want more substance from her campaign, not because it won't work this way, but because this way is working so well. She has the opportunity to make some progress while still tripping him into pools of his own filth.
