"I've sturdy boots for a reason, don't worry." Murmuring while tucked close is second nature, he's lost track of how often a dance at a gala was the only opportunity to exchange information during more delicate negotiations throughout the years. Becoming versed in etiquette and diplomatic overtures was a requirement of any seasoned Jedi Knight; and while all those skills are not applicable in this moment? Adaptability and dexterity certainly assist in guiding Castiel through the steps of this dance. Steady and somewhat sensual (potentially, but they're far too light and faintly fumbling in a way he finds more endearing than anything else to truly be seen as such), Obi-Wan leads his partner across the floor.

Deftly weaving around the other couples, laughing off the slight missteps as Castiel focuses in and picks up the nuances of the footwork, warm and solid almost as stone, steady. Once they're both certain, Obi-Wan allows his awareness in the Force to prevent them from turning into anyone else, from being bumped into or cut off. The intensity of this angel's gaze is-

Not unsettling, nor is it awkward, not to him. He is not human in the way he appears to be and that makes these oddities acceptable. Blue meets blue flecked with green, Obi-Wan's own expression utterly serene, his soul buoyant and thrumming with simple joy- of movement, of community, of communion with another soul similar to his own. "Yes and no. Diplomacy is of great import to our cause as negotiators, and I've picked up more than a few courtly dances in my time."

A pivot, a step in and past Castiel, pulling him in close as he twists until he's standing behind, hand on his hip, other on his palm to guide him through a reverse embrace- lips by his ear, voice palpable with how his chest is pressed to Castiel's spine. "This particular variation is popular in a great many artistic planets, usually played later in the evening after there's been a great deal of wine imbibed and couples are feeling more- amorous? With the close embraces required it makes for an excellent opportunity to discuss delicate matters plainly, especially with the rest of the attendees distracted."

Another line of music, another pivot as he murmurs "lean back, trust me-"

One hand skims up to clasp Castiel by the nape of the neck, guiding him backward in a dip- held steady for all his weight and catching him neatly as he drops, guiding him back up with a nudge of Force to help him down and back up with a measure of grace. Once back in position he nods, proud. "Very well done. You're a quick study, my friend."
