In extensive career retrospective interviews published across Entertainment Weekly and E!

However, decades of maturity allowed both artists to heal completely. The pair memorably reunited on screen for Lynch's 2017 Twin Peaks revival, with MacLachlan emphasizing that they remain "great friends" and celebrating Dern as "kind, understanding, smart, beautiful, and empathetic" with an "excellent sense of humor."
