Now she has accepted the calling of Captain, and it genuinely seems that she has committed herself to a calling higher than herself.
At the beginning of Season 2, Sara was completely ready to abandon the team at a moment’s notice to accomplish her personal objective of killing Damien Darhk.
Sara has been a lone wolf since her earliest days as The Canary on Arrow, but the moment Rip acquiesced The Waverider to her was the moment she became the character that we’ve been waiting to see.
This development for Sara’s character feels particularly important because it shows how far she has come over the course of this season — not to mention her entire existence in the Arrow-verse.
