Peter enters the flat.
Caitlin walks into her Cork flat with Peter, where Peter finds a few canvases that Caitlin painted. Peter pulls out the box and tells Caitlin that he has to face who he was. Looking at a blank canvas, he sees flashes of something, picks up a paintbrush, and paints in a trance-like state. Caitlin and Peter look at the completed painting and conclude that it is set in Montreal. Caitlin then receives a phone call that her brother has been electrocuted; Peter and Caitlin leave the flat for Wandering Rocks.
