Vince fired at the creature, sure to at least wound. He was quickly proven wrong. Maybe the disease, or maybe just the creature was so dammed fast, but he only managed to burn a few scorches on a nearby mushroom. It is very bad thing to be such an unlucky fellow, after all.
Meanwhile, CX stepped back from the creature attacking him, and fired a short burst at the oncoming beast. The results, however, were far from what he have expected. Again, the beast proved to be far to fast to get simply gunned down, and effortlessly dodged all blaster bolts.
However, it did not attack CX, nor even Vince. The beast have apparently noticed your Jedi Master, and found her really attractive... in a manner, at least. Both turned towards her, as she tried her best to hide, and both charged. To your surprise, even in handcuffs, the twi'lek managed to evade them both, in a way to fluid and elegant for you to ever dream of replicating.
