The second Angelina saw the flash of red hair she grew even more angry. Ang hadn't even thought it was possible, but apparently it was. It didn't even matter which one it was - she was angry with George for disappearing and making her worry, she was still angry with Fred for being a right prat, and she was furious with Percy because he had let Oliver go off alone, and she was angry with Bill for not implementing a real plan. Realistically, Angelina would eventually come to the conclusion it wasn't Percy's fault, but she needed someone to be mad at. In fact, if a student had wandered across her right now Angelina would have taken points away and screamed at them to leave her alone.
Where the hell was Stan? Why was he taking so long?
As Percy neared, Angelina narrowed her eyes. "Oh, and you are? The only reason he's out there is because he doesn't think you can protect yourself! At least him worrying about me is legit since I don't have magic anymore. I'm not going alone, anyway!" Every word Angelina spoke was filled with anger and resentment. She was furious with Oliver, but it was being deflected onto Percy. If Stan had showed up first she likely would have yelled at him too. Right now it didn't matter, yelling at people gave Angelina blissful seconds to forget about Oliver and his stupidity.
"Why are you even here!?" Angelina snapped. Out of all the people who were going to want to help, Angie was landed with Percy.
