And then there is a reception! Bella does not quite work around to asking Kazul about the King's Crystal. She's married into a family that is friends with Kazul and will have another opportunity. She mingles, she samples refreshments, she beams at Sherlock a lot. She walks away from people who make catty indirect remarks about her commoner origins. (She's a princess now. She has a crown to prove it, set on her head shortly after the kissing part. Tony made it for her and it's utterly lovely.)

And then all three princesses (of course Tony is coming along) are off on a honeymoon! To the beach! They spend a lot of time in the seaside cottage and not nearly as much time actually on the beach.

Bella brings her magic things. The most clinical conception in history takes place (and is then celebrated, rather less clinically). Bella thinks it worked, but there's no way to be sure until Sherlock starts exhibiting the usual symptoms.
