In The Summer I Turned Pretty season 3’s finale, Conrad leaves Paris by train to reach Brussels.
The destination is part of Conrad’s travel plans for a conference. He visits Belly in Paris on the way, creating the setting for the finale’s reunion before he continues toward Belgium.
The train departure becomes crucial when Belly realizes she wants to be with Conrad. She chases after him and declares her love as the already-departing train leaves, leading to their reunion with a kiss.
Brussels is easy to confuse with Paris because most of the episode takes place in the French capital. It is also distinct from the city where Belly is living: Paris is her location, while Brussels is Conrad’s onward destination. The finale is titled “At Last” and premiered on September 17, 2025.
