As an answer to Frey asking what the problem is, Robin shows him her laptop screen: a Vance Lee has been assigned as her roommate, which is highly suspicious as her request for a single room had already been approved by the university.
Before Robin gets too paranoid, Frey points out they haven't made any moves yet, so it's unlikely Solar Eye has noticed them and the issue could have been caused by a number of reasons, from just a glitch in the system, change in assignments, to their worst fear: a government spy. Regardless of the situation, this means Vance is a liability until they can learn more, as Robin's activist lifestyle would mean a roommate would question her extended absences from the room. Frey then tells Robin not to worry and to carry out Operation 2G1H and he'll take care of Vance.
Back at the Lee family's home, Vance is helping Alex get around the Great Firewall and asks how she got temp-ID banned from the internet, with his sister simply responding he wouldn't understand the purest form of love.
