She called out Excadrill to help rescue Axew from between Pendra's horns but it stayed in its curled up drill state until after Axew was rescued. Pendra though was still raging and it kicked Excadrill and got it angry. It then drilled underneath Pendra and then set it flying.

Excadrill didn't always want to obey Iris when its asked to do something. For awhile, it was stubborn but Iris' Excadrill was able to overcome the feelings of resentment and lost of trust it felt from the battle against Drayden's Haxorus. After relating her experience to Ash Ketchum and Cilan, it became more clear to Iris that she was not fully understanding her Excadrill's feelings. Iris apologized to her Excadrill as she finally realized that her Excadrill knew after the first hit during the battle against Drayden's Haxorus that they couldn't win against it.

Mastering Focus Blast

Iris eventually realized that her Excadrill didn't know any moves that it could use to fight with from a distance.
