I love Section 31 sudden reveals of .. Section 31.
I have nothing against the concept of Reed being in the Section, that would've been cool to find out in season 2 or something.
It really contributed not a thing to the plot's problem or resolving it. They just played a mild part on causing the problem, that really was already underway. Aside from Reed getting some angsty screen time, which was well done.
In the other episode they're in they play a similarly inconsequential role aside from taking up screen time.
