"Don't you dare talk like that."
Barbara didn't mean it to come out harshly. She was just... startled. You were having a rough day with the training simulator. It happened to everybody. Some days you just weren't in the zone. Babs hadn't even meant to be watching you; she'd come down to the Batcave while you were in the middle of an exercise, just to quick log in on the Batcomputer, do her standard checks. Heck, you likely didn't even know she was there.
Which is probably why you'd burst out in that self-depreciating rant after another simulation failed, thinking nobody was around to listen in. She's heard it from frustrated family members before, especially when you're still new: 'I can't do this, why am I even here, I'm screwing everything up, he never should've let me in here, they should just kick me back out...' Even if you were just venting frustrations in a rush of un-thought-out words, she hated to hear it. Because even if you were 'just venting', the root belief was clearly buried in there somewhere.
Barbara frowns and shakes her head slightly, backing her chair away from the computer enough to turn to face you and move herself closer to the platform you were on. No point shouting across the Cave. Because she didn't mean to be harsh, but she wasn't just going to sit here and let the newest member of the family think that sort of thing about themselves.
Big Sister mode activated.
