The Witch was certainly sceptical about a couple of things, such as how alcohol "helped", or why they were in such a place to begin with. None of what she was witness too seemed very productive, or at least contributed to her training, but Dean was the teacher, so she tried her best to at least appear as though she wasn't completely lost. She also felt like beating Dean to a bloody pulp the moment he called her "love"... But as they got closer and closer to the epicentre of this cavalcade of drunken insanity and debauchery, they stopped, and Dean told her this is where her training would begin. And as he explained to her exactly how she could pull off the first part of her training, Dean disappeared into the crowd, quickly blending in amongst the rowdy bunch of drunken slobs, quite effectively at that. That must have been why he said that "liquids" were important to this training, so that he could blend in to this morally decrepit environment as much as possible... Without proper guidance, it would be almost impossible to find a single person amidst all this chaos. And so Morrigan did as instructed.
She closed her eyes and began gathering both Lightning and Wind Release Chakra in equal proportions and attempted to combine the two. She reasoned that, like Wind, sound was a non-solid Element, lacking a physical form that one could "touch", and therefore logic dictated that Wind Release would form the "template" of sorts for the Element, while, like Lightning, Sound was composed of vibrations, with Sound utilizing both high and low frequency vibrations, while Lightning could only be performed with high-frequency vibrations. Nonetheless, Morrigan combined the aspects of the two Elements she reasoned formed the basis for Sound, and proceeded to concentrate the gathered Chakra in her lungs, as Dean instructed. Releasing the Chakra in tandem with her breathing, Morrigan waited for any kind of effect to take place.
While there was no immediate results, after a few moments Morrigan began to notice shapes forming around herself as the sound she was beginning to emit from her breathing was bouncing off of solids, and returning to her with a form of information she never knew existed. And as she grew accustomed to the way this new method of sight worked, she began to change the ratio of Chakra, adjusting the frequency of the inaudible sound she was producing. In addition to this, she also found her sense of hearing becoming far more effective, as she focused on specific areas of the environment, searching for her teacher. She heard the story of a man in a bar several blocks away, spinning a tale of woe and deceit brought upon by his own neglect for his partner, while not too far away several men were singing a song with... "Questionable" lyrics. It was this nearby act of joyous singing that brought Morrigan's attention to the quiet singing that had just began moments ago. The voice was almost familiar, and the lyrics were far more inspirational than the drunken chanting coming from down the street. Morrigan decided to focus her attention to the West, and sure enough there he was, casually seated, alcoholic beverage in hand and performing the most absurd motion with his hands. As Dean was, probably, distracted by his air guitar solo for the masses, Morrigan approached from his blind side, pulled up a chair, sat down and addressed her teacher.
"Shall I pretend to play the drums? I'm certain that together we could put on a show likes these people will never remember."
