I've seen this episode several times through now, and this is some of what I'm thinking as I do so:

1).  I want to see what's in that match box!  It produces a rare, genuine Sherlock smile!

2).  I would give an obscene amount of money to see Sherlock holding John and Mary's baby.  I wonder if it would soften him at all.

3).  I love Mary - how she likes Sherlock immediately and how she doesn't stay put when John tells her to.  And I like how John's first reaction when he learns they're in danger is to kiss Mary.

4).  I love how The Woman interferes with Sherlock's thoughts while he's trying to deduce.  Quite telling, I think.

5).  I cry during his speech and also when he leaves early - and I'm mad at Molly for not going after him.  I'd rather have less of the real thing than all of a bad substitute - even if it meant no sex (at least until I could convince him to try it).

6).  Drunk Sherlock is a riot!  I wonder if he'd be easier to take advantage of . . . Did I just say that out loud?
