Problem Statement

Let ABCABC be an acute scalene triangle with incenter II. Show that the circumcircle of BICBIC intersects the Euler line of ABCABC in two distinct points.
(Recall that the Euler line of a scalene triangle is the line that passes through its circumcenter, centroid, orthocenter, and the nine-point center.)
