After class, Barbie meets with Steven and Brian in the library. "Hi, guys," says Barbie. "I tried to send you my designs, but I ended up crashing my laptop--and Skipper's, too! Could you guys help me get back the lost files and repair both of our laptops? Only if you'd like, though. I can get it done myself, it'll take a longer than if three of us were figuring it out together. No big deal either way."
