Only you
A head start; that was what Sil needed most. Holding the flask in his hand, and the power of all three abilities, Sil was using the Teleport ability to run away as fast as he could. His normal speed wouldn't cut it, and he was thankful he had such a handy ability for the current situation.
Still, there was a limit to how far he could teleport, and each time that would only delay him a little longer.
He knew his Sister and Brother wouldn't have been defeated by that single punch, and they would be back only getting angrier than before. Now, while they were hurt, there was a chance to escape, and what better way to do so, while Quinn had super speed in his current form.
What they weren't expecting was just how fast Quinn was. Even with him teleporting constantly, which was almost instantly moving from one place to another, he was slowly catching up to him in his Bloodsucker form.
