Lecture

An animated character in a dark suit stands with their back to a green chalkboard covered in chemical equations and Russian text, holding a piece of chalk and making a gesture with their right hand, then turns their head to the side with a surprised expression. The scene cuts to a live-action man with dark hair and a patterned shirt, holding an open book and looking directly at the camera with a surprised expression. The scene cuts back to the animated character, who maintains the same pose and expression.
