Worry comes naturally.
When you watch the end of Arrow s2 and have Caity at Comic Con, as if she was part of the Arrow cast, just for them to literally throw her character off the roof into the trash and then a few episodes in, see that they literally frigged her, yeah worry comes naturally. Imo.
And LOT has been forcing Ava into the captaincy all season. Now Sara is literally gone. What a coincidence.
And Phil Klemmer doesn't give me any confidence. Even goes into Ava when Asked about if Nate will morn Zari 1.0. He won't have time because he will have comfort Ava. Oh he says Sara and Ava are like the parents of the Legends but for Phil, "With one parent gone, I like the idea that Nate is a bit of a goofball and a bit of bro sometimes, but that he's really gained some real wisdom and he would be able to support what's missing".
Neither of the interviews Phil did, talk about where Sara will be and do while being kidnapped or how she might feel. And now having to wait almost a whole year, I'm just a totally unamused fan.
