I think Snapper's lines don't count as pep talks because he rides the line between "get your shit together" and "I treat everyone this way," the first of which is reasonable to a new/inexperienced reporter and the second of which is character (ie. he's an asshole though if this show has its way he will turn out to be an asshole with a heart of gold)
Same :o wow show wow :o
I feel like this and other scenes tend to undercut the idea of female empowerment that supergirl should/does stand for. I'm not saying that being vulnerable or cute or inexperienced in dating are bad traits so much as they seem like clichés or, at worst, lazy stereotypes.
It seems often the show wants to have its cake and eat it too, especially when it comes to the humor. For example, it's realistic that Kara's sister Alex, who grew up with her, might poke fun at her like in the most recent episode, but to have Winn doing the same when not too long ago he treated Superman like *a god walking the earth* seems disingenuous to the show's theme.
