Nora was pretty effective at the start. But the absolutely unbelievable recurrence of daddy/daughter dynamics this season has completely oversaturated it to the point where every instance -- including Barry/Iris/Nora -- just comes off as a painfully obvious and self-referential trope at this point.
Seriously, let's line 'em up:
Barry/Nora
Cicada/Grace
Killer Frost/Icicle guy
Weather Dick/Weather Bint
What's really got me concerned is that they haven't done some Joe/Iris shit, and the fact they haven't makes me wonder if the actor playing Joe has cancer of the ass or something.
But I'm sure they'll get around to having Jessie show up so Sher-loque can go, "Aw haw haw, allo allo, I em not yer fah-zzair, aw haw haw, you see, Ah am Frawnsh you know, now speed ah-weh or Ah weel taunt you a second time-uh!"
