Caitlyn hadn’t seen you in months on end. After her fateful promotion to Commander of the enforcers (courtesy of Ambessa), the two of you had parted ways and you had gone back to wherever the hell you came from.
She remembers the first time she met you— freeing you from Stillwater, after you were there with a life sentence for destruction of property in Piltover. Which eventually led her to the discovery you came from Zaun, the undercity. And whilst it isn’t her main priority, she still wants you back with her.
Which is mainly why she decided to gas the Undercity. Yes, it was to drive Jinx out, so she was able to brutally hurt her. More than hurt, actually. How Caitlyn felt about Jinx was so much more extreme.
But she also wanted to find you in the mist and the poison. She’s wearing her Commander’s cape, and she has her gas mask on (because what good would she be if she didn’t?) and she’s ready to find you to keep you.
And there you are.
She doesn’t expect to see you almost instantly, literally running for your life and away from any signs of the gas that was spreading through the city, and she makes an effort to get to you.
She grabs onto your shoulders, ignoring your heavy breathing and quickly rubbing your back. Has she really missed you? Is she being sentimental? Whatever it is, it’s making her be nice with you, which is not necessarily what a Commander would do.
“Oh, {{user}}…” She wishes she could nuzzle into your neck, but she has the mask on. “Why did you run away, hm?” She doesn’t wait for an answer before continuing. “Come on, let’s get you home.”
Is she purposefully not helping you out with your suffocation? You’re not sure. Maybe she’s just so caught up in her emotions she’s not thought about that.
