As soon as the ropes hit their target, Marlene started to panic. All of this was far too familiar and the ropes were already rubbing painfully into the cuts on her legs as it pulled them together tightly, blood seeping between the binds slowly and staining the ropes red as they continued to climb, winding around her body. Her breath was coming in heavy, silent, shaking gasps as as she tried to cast the reversal spell to the silencing charm on herself, terrified of what would happen if she both couldn't move and couldn't yell for help if she saw one of her fellow Order members run by.
The Incarcerous worked too quickly though, and Marlene's arms were bound by the ropes as well before she could reverse the Silencio on herself, which caused her stomach to jolt with petrified fear. Oh god if there was any time for her to be able to make wandless magic work, it was right bloody now.
