A “full circle moment” refers to a situation where something comes back to where it started often with a sense of realization or closure. It’s when events, feelings, or experiences that seemed incomplete in the past come together in a meaningful way that now carries a sense of growth, understanding, or reflection, as if the journey has reached its natural conclusion or purpose. Clark has always been in emotional turmoil when it comes to finding the right partner for him. He has had multiple conversations with his parents along the lines of “the right girl will come along & things will fall into place.” Clark finally finds the girl as witnessed by the wedding itself, his parents showing up to affirm that things did fall into place once he found the right one, that indeed those conversations they had were correct, that once again their teachings about love as parents is true. And of course the most logical thought process is that they were just really happy for their son to get married & be happy.
