Here’s something I noticed about Gravity Falls episodes and the explosions of ships in the fandom (it’s not in any particular order).
Season 1: undertone of one-sided WenDip
Double Dipper: gave birth to Dipscest
Into The Bunker: end of WenDip
Soos and the Real Girl: Soos and Melody
Love God: wraps up Robbie and Wendy. Tambry and Robbie start dating.
The Golf War: Mabicifica
Sock Opera: BillDip bomb detonates on tumblr
Society of the Blind Eye: Mermando and Mabel officially end
The Northwest Mansion: Dipicifica shippers will probably explode like BillDippers did
