Could be, there was never any implication that Harry knew the existence of Gideon, as it was last seen in Season 1 (I know it appeared in Season 2 but only thawne spoke to her/it) Also throughout the season, Thawne kept on being mentioned when being mentioned as a planner. Like in Enter Flashtime, "Looks like we have a planner." "Just like Thawne" and then Harry eerily pulls out a photo of Wellsobard and says it again, "Just like Thawne" Even in the recap of what happened in the season (In the previously on the flash part) The clip of Harry saying, you guessed it, "Just like Thawne" appeared, I'm serious watch it again.
