Noel and Anna jumped in opposite directions, confusing the earthworm.
Anna was stronger than Noel. However, it was clear that Noel actually took control in most situations.
If he chased after the wise, there would be a chance of falling into a trap. If he chased after the strong, he might get injured.
The earthworm had to consider its choice carefully since one mistake might lead to its doom.
As one would expect from a Superior Demon's intelligence, the earthworm actually chose an answer aside from Noel and Anna.
The Superior Demon actually turned around and planned to head back to the tunnel. This way, Anna and Noel would have a hard time stopping him. In addition, the Superior Demon could easily make another tunnel with its mouth, making an unpredictable route and burying them inside.
