Jesse and Petra: Maybe the bridge scene?

Lukas and Jesse: I honestly don't know.

Lukas and Petra : When Lukas decides to stay and wait for Petra...

Jesse and Aiden: NO CLUE.

Olivia x Lukas: How did that ship form, actually?...

Ohhhhh, maybe when Jesse goes with Axel to find Magnus...

Honestly not sure.
