Okay, so in The Flash, Season 5, we see Nora travel to to other times, specifically 2049. I have no problem with this, as all seasons have dealt with time travel in some way or another (except maybe season 4, where I can't think of a time travel instance off the top of my head).
What I find weird however, is some subtle attempts to create tension because of her time travel. For instance, S5 has a habit of starting an episode where
Nora is in 2049 where she talks to Wellsobard (Eobard Thawne with Well's face)
Then, it will cut to the present where Barry and Iris will ask some kind of question like "Where's Nora?" The implication being she might be late or something because she's busy time traveling doing the spoiler.
That's all fine and good, except she can time travel. She could spend 5 years, or even 30 years in the future and they wouldn't know it (except for the fact she might look 30 years older, but besides that). Of course she's not going to be late.
Am I missing something? While her actions during her travels are relevant to the story, is there a point to attempting to create tension by starting an episode showing her time traveling or is this an over-site?
