Not really...cos there didn't seem to be any connection.
Just funny that her outward journey was as a fugitive and her return one was with her husband...

Not a headscratcher but a nice observation - there is a "veiled bride" in Tbilisi:

I do not think so, Schmiezi, I checked all the episodes. The perfume references stop after TAB. 

Here is another headscratcher: What becomes of the Ajay flash drive, the one containing Mary's whole dark past, the one she wanted to protect John from because he would stop loving her?

The drive, i.e. Ajay's copy, travels to Tbilisi, is hidden in the bust, sold to England, stolen by Sherlock, stolen by Mary, travels all over the world to Morocco - and then, nothing. It is never mentioned again. Its contents do not matter. I find it really difficult to understand that they placed so much importance on Mary's past in HLV and then, in S4, the only thing we get is the Tbilisi incident in which she was a victim. There was nothing about it that could have stopped John from loving her. Can anyone explain this?

No.

From a Radio Times interview with Amanda:

"There was a really lovely dinner scene with John and Mary when they have this really lovely talk about how scared she is about being pregnant or having a baby and that they’re drifting apart. It’s a lovely three-page dinner scene that we did and we loved it and it never made it, I think because it was running about four hours and they had to get it down to an hour and a half. They’d just come back off the plane – or Mary was just about to go off on her journey – and she was just saying that she’s flying out of control and she doesn’t feel like she’s grounded because she’s trying to tell him who she really is and she can’t and he’s drifting off and they’re not really communicating. It’s a really lovely scene but it never made it and I know why because sometimes you don’t need that – less is more. But we loved doing it."

Ahem. Four hours? I wonder what else has been left out. Maybe all the things that would explain the headscratchers? And I wonder why they kept the play-acting plane scene with Mary which did nothing at all for the plot.

I agree but I still wonder why they did the plane scene at all. And the wheelchair moment. It did nothing for the plot, it was not funny, and the focus on Mary's escape pulled away from Sherlock as well. 
 

True. Although, honestly, I think Sian's disguises and accents were much better.
