#1 - Root of the Problem

The gigantic tree man looks down at Mist and Cammy. He's barely acknowledging you, and definitely not treating you seriously and is planning to simply push his way past you. A lumbering branch of an arm swoops towards both of you, likely to push you out of the way.

There is indeed a large crowd gathering. Quite a few screams of panic and awe, and not just from the bank robbers. They weren't prepared for this and look around desperately looking for an exit. The one with an automatic weapon who called out Rosethorn has dropped his gun entirely and has collapsed to the floor as he flexes his thorns.

The rest of his team split up and break, similarly freaked out. The woman with the handgun springs out from behind her cover and is trying to run into the crowd. The two with a shotguns are trying to run down an alleyway that you know leads to a dead end (must not be locals) and one decides to chance his way to the van carrying as much loot as he can; which does mean running past at least one of Rosethorn, Kingfisher, Quasar and Whimsey.

What's the plan team?

Cammy takes on the form of the floor, a mixture of linoleum and concrete. It's not the greatest defense against the branches but it takes the brunt of the branch, bending the wood around you, and it gently comes to a stop landing between you both. However, you now have his full attention. The branches fix themselves to the floor and sprout additional branches of their own, separating you both, putting Mist outside the store with the rest of the treeman and trapping Cammy inside of it.

The thug goes hurtling through the air and bounces, almost comically, off of the treeman in the doorframe. He turns to face you; you have his full attention. "Run along now sapling, unless you want Old Willow show you a thing or two". He stomps towards you, slowly but angrily, leaving a line of roots chewing through the concrete as he does so.
It's still a weird experience for you to phase through living matter; even if it's just mostly plant matter there's that uncomfortable feeling as your molecules pass through cell matter, connected to what's ostensibly a living being with a heartbeat behind it. Nevertheless you pass through, reach out for Cammy and get through fine.

You really, really don't want to do that again; not for a while. You're going to take a powerful blow if you phase through any part of Old Willow again this scene.

What now?
