Tried to be, did that count? The Bishops had never really been about familial closeness. Susan technically wasn't even her real sister, which created a weird buffer, but she grew to love her like she was and Kate couldn't stand to think that at some point, as they laid in bed together, that Susan took her last breath and had her last heartbeat right there beside her before turning into a cannibalistic corpse. "It's complicated," Kate murmured. How close they were, or were trying to be didn't even matter anymore.
It was a loss, and Kate accepted it, but she was frustrated, because it shouldn't have happened. That wasn't a mistake she could fix. Her face, which she tried to keep neutral turned into a frown, brows contracted as if pushing away the desire to cry again, and she looked up at Tony with restraint. Kate needed her defenses; without them was how she ended up with tears in her eyes and a broken heart on display, and if she hadn't been so resolute in keeping her emotions at bay, this might've turned into an unwanted sob fest.
Still, she showed him no resistance, but might've been holding her breath, and let him remove her guard, at the same time, trying to assure him with a weakened smile that she was okay. Mostly okay. Kind of okay. Okay enough.
