The Doctor didn't manage to get out quite as fast as Sarah Jane, but she wasn't far behind. Likewise, she had the sonic screwdriver out fast, but not quite fast enough. The doors were already opening, and the Doctor didn't honestly have much to do but dig out a small bottle of vinegar, she knew she'd had some somewhere, and throw it at the advancing Slitheen while a trio of children- Maria and Luke? Who was the third?- made a break for it.
