Todd Helbing did say that the upcoming episode would look into just how much of Oliver’s dour pragmatism will be embodied within Barry, and I dare say that it won’t be such a bad thing if Barry has a small pessimistic voice on one shoulder warning him against doing all of the impulsive things that he’s already been trying to avoid doing in front of Nora.
If anyone on this show could use a more balanced perspective, it’s Barry, especially if Reverse-Flash is looming large for the rest of the season.
