Phin was panicking, running through the halls frantically, trying to find where Betty and Sam were. Betty and Sam. God, this couldn't have been any worse. Betty could hold her own in a fight, but not against Sam. Not tonight.
Finally, he spotted them and momentarily stopped in his tracks. Betty was injured, and Sam was obviously overpowering her, and he couldn't... well, he couldn't just stand there! He started running again, as fast as he could, and shouted, "Betty! Sam!"
He skidded to a stop as he got closer to them, then threw himself between them, shoving Betty behind him. "Both of you, stop it! Just stop!"
