I don't think anyone thought it was going to be anything more than a goodbye scene. Of course Barry and Caitlin weren't going to make out and confess their love for each other right before she left but that's not the point because baiting a couple is not about being "obvious". It's either about coming up with AU scenarios where the crackship is canon or using writing, directing and editing tricks that leave the impression that there's something more going on there even though nothing will come out of it and the overall storyline won't be impacted.
In my opinion that scene was bait because of the slow motion ( an editing trick that gets mostly used to imply romance ) and because of how it was framed with Barry being left behind in Caitlin's apartment for a "look back" shot.
That's the only time I thought they were baiting SB this season. And I already said that from a writing/storyline perspective Frost and Ralph were given more scenes that could mean something more than friendship if they ever wanted to go there.
I wasn't looking for it. It's the other way around. That stuff was blatant and put in there to beg me to see chemistry and potential.
What fuels those shippers into thinking their crackship has a chance is the show baiting them, not what WestAllen fans think. Let's not blame us when it's the writers that give ( gave ) them false hope.
And I don't think every Barry and Caitlin scene is bait, just that one. The last part to be specific, not even the entire scene.
And I have reasons to be threatened. Not about SB ever happening but about the fact that these writers would rather give crackshippers a "bait" goodbye scene ( and DP is not even gone for good ) than give the canon couple more romance moments. I am threatened because they are going to great lengths to present Caitlin Frost as this badass hero who's also vulnerable and gets saved by Barry and comforted/praised by the entire team but Iris is written as a SBW who constantly needs to prove she's no damsel in distress and couldn't even cry about her husband dying in Crisis months after her daughter had vanished in her arms.
WestAllen don't have to break up and Barry doesn't have to dump Iris for Caitlin for me to think that these writers are being unfair/shady/racist about my favorite characters and ship.
This goes back to my point. Cisco is Caitlin's bestie but he didn't get anything at all let alone a goodbye scene complete with slow motion and a "look back" shot.
