Tatum had been regretting the fight pretty much since it had happened, but her stubbornness had kept her from admitting it to her girlfriend. Instead, she had done her own share of moping, hanging out in her room and lazing around after classes, catching up on video games and internet hijinks. While that had been amusing for a while, it wasn't keeping Mack off of her mind, and it wasn't helping her feel better about pushing away the one person she had left. Hadn't that been the whole reason for the fight, that Mack was all she had and she couldn't stand to lose her?
Whether she lost her in some duel against a dastardly villain, or she lost her over a stupid fight, she would still be gone. She had said harsh things that she had felt bad about almost immediately, but still she couldn't stand to make herself back down. She was worried sick and terrified about losing the other girl, of seeing her get hurt, and even if the watch duty was just supposed to be an observe and report mission with lots of staff, there was still that chance. Tatum's anxiety, and therefore her life, revolved around the idea of chances, the mere chances of what if. Anything bad could, and often would, happen. She had always been a strong believer in Murphy's law.
She had been wanting to apologize, even if she wasn't ready to drop the subject of watch duty, for a day or two now. Curled on her side on her bed, she had her hood pulled up and her eyes focused on the game in her hands when Mack knocked on her door, making the redhead tense up a little. She wondered who it might be, but she had a feeling she knew, and it made her heart skip a little beat despite herself. When the blonde spoke, she felt relief washing over her, even if she knew the talk they were about to have might not end any well than their earlier talk on text.
"D-Doors open," she called back after a few moments of quiet consideration, clearing her throat a bit and beginning to scoot herself up, finding a half-sitting position leaned back on her headboard. She just kept playing her game, watching that instead of waiting for the older girl to let herself in. She didn't want to back down right away and run right into the blonde's arms. She was still mad at the core of everything, despite the other emotions tugging and pulling on her.
