He had seen his mother do a ton of non verbal spells without her wand. He knew in theory, that the wand helped channel magic but you could do magic without a wand too. He outstretched his right hand putting all his focus into it imagining a wand in it and screamed "accio". The sickle quivered but nothing much. Ron was screaming, the plant was hissing he tried it again, this time he felt his entire body radiate with magic. The sickle came flying and if it wasn’t his seeker reflexes, it would have taken his head off. He hacked off the vines holing him and fell to the ground. He momentarily considered leaving Ron hanging but then thought how pissed Hermione would be and dove back into the plant’s vines again hacking them and trying to reach Ron. The Tentacula was not having it and it started to fire spiky spore-like balls from its mouths at their Draco. After about 5 minutes of battle. Ron and Draco were sitting as far away from the Tentacula as possible that was quite hacked up and still flailing it’s cut vines in rage.
