Mike Vogel plays Brock.
Brock is Laura’s (Christine Woods) boyfriend, he is a carbon copy of every asshole from every John Hughes movie. Laura cares about Brock and sees him as a good choice for her, he’s successful.
Unfortunately he could care less about her son (George Dalton) and generally chooses to ignore anything that doesn’t fall into the categories of luxury vehicles, crossfit, and his own general awesomeness.
