“Fine, but let’s hurry!” She bolted ahead and took the tip of Celestia’s wing in her teeth.  Her horn began to glow.  Celestia realized what was about to happen, but she was too late to stop it.  A blinding white light engulfed her, followed by a violent jerk on her wing and a flare of heat.  The sensation faded just as quickly as it came, and Celestia immediately yanked her wing back from Luna.
