We already knew that; Blake's hearing has a boost from her cat ears, which have been seen twitching towards noises inside her bow.

Also, the stuff that leaked out of his severed tail was well below the venom gland (which is the bulb at the end where the stinger is) so it might not be venom to begin with, could be blood or whatever fluids he uses for controlling it since scorpion tails are powered by a combination of muscles and hydraulic pressure.
