You couldn't be more wrong if you think everything is going to calm down now just because Accelerator defeated the members of Scavenger. Despite the brief interlude, the battle is far from over. After all, only the enemy's pawn has been taken off the board. There are some odd animation in this episode and the studio did cut some corners but overall it's still fine and it's not that distracting. P.S. If you think about it, this is the first time that Yomikawa got involved with the magic side seeing that this is before Vento of the Front infiltrated Academy City.
