These are rated from the least significant one to the most significant one as I see it. I think the ultimate one is the re birth of Killian, because there was no better reunion than after they had their ultimate goodbye, thinking there’s no chance in hell (see what I did there?) that they will meet again.
For the second most important I chose the bed scene. Even Jen knew the importance of that one when she excitingly added the bed to the bed scene lol.
