They don't seem particularly interested in walking away. The sister with the swords tosses a net at Tim, largely because he's the only one small enough to carry off that way.

It's a miscalculation. Bee is faster than his size would suggest and he intercepts the net with an armblade. The silver strands are tangled up with it and Bumblebee wraps it up to further secure it before pulling back as hard as he can. The sister is sent flying towards him as he swings back and punches her right in the face.

She teleports away, not willing to risk another oversized punch like that, while the other sister swings her kusarigama at Tim.
