I loved Henderson's calm acceptance that Lois had solved a murder for him. It's only logical, after all, given how he explained that murders were more important the last time she came to visit him at the police station.
Guessing that Bob and Angelina knew each other because they were both "science" majors does grate on my science-major brain a bit, but maybe that's just how it is from the perspective of a journalism major. Now, Bob is physics/chem, and Angelina was a pre-med workaholic, so say she was bio/chem; so both being chemistry majors and of the same year(?), yeah, I can see that they would know each other.
