Robin is fast, a reckless disregard for regular limbs and joints'll do that, but she's not as fast as a giant wolf, so she suddenly cuts left when Tereza gets too close, hoping she'll pounce past her.
Tereza seems to be mentally prepared for that eventuality, but momentum's still a thing and she loses a lot of steam as she does a skidding left turn necessitated by her speed and bulk. It takes her a moment to find get her purchase back and start building speed again.
Robin can't help but laugh at the giant wolf skidding past her before cutting another corner, continuing to run while holding on to a nearby tree with one hand, arm stretching out behind her.
Tereza slams into the tree, which looks like an accident at first until one of her hands reaches out to grab the stretching arm as her shoulder tries to pin the hand to the tree.

This was, perhaps, more difficult than Sam had originally thought, as the blanket seemed to be trying to shy away from being actively wrapped around Sam as much as possible.
Robin had planned to sling-shot herself back when Tereza came after her. She had not expected her to be clever about it so now instead of catapulting herself to freedom she's inadvertently flung towards the angry wolf.
Robin has the mass of an average person, but getting yanked through the air she instinctively changes her consistency to be pretty malleable, so the impact isn't too bad. It does mean that she kind of splats into Tereza's hand and around her splayed fingers in ribbons, wrapping around her forearm like a braid.
"I mean," Sam's blanket toga explained. "This was her idea from the very start. Thought she could get one up on a less experienced war goddess and her lovers. Never could pull this off back home."
"We have high-tech stealth planes, an alien-inspired simulation room and a lighthouse which technically expands into other dimensions. I am sure that we have the capacity to wash some fabric."
