I guess since she was only credited as being in 7 episodes lets them make that billing (missing in episodes 1, 3, 4). But then that allowed her surprise appearance in episode 5 that gave me a reaction like in the video I linked, hahaha. But I also wonder if there's a cost implication, since (outside of the senseis) she's the only one with legit past acting experience? So would probably cost more to give her full billing? Though she's certainly the face of Cobra Kai in S4 (with Robbie) and with that Netflix money backing the show I better get my 10 episodes of Tory!!!
And I didn't mean "filler" as in nothing changed but it did feel a bit like "going through the motions". Like I figured before the season even started that this would all end up in a WWE-style "loser shuts down" match at the tournament and sure enough that's where we ended up. Though it does get me excited for Season 4 and I still like the Hawk redemption arc and Robbie descent to the dark side (figure him and Tory will be a thing in S4 too...)
And we'll get Dojo Odd Couple shenanigans that'll be fun to see. And yeah, Terry and Robbie, didn't even think about that! Robbie as the new Mike Barnes, hahaha. Just hope we don't have to wait a year and a half this time!
