If she hasn't seen any of Sherlock, I'd go with A study in Pink.

If you both are rewatching... well, I'd say Reichenbach, all the way 

good choice Molly!    Especially since it's been a while since you've seen TRF.   Have fun!

Here in the U.S.,   TRF  is finally being broadcast this weekend.   I'm going to watch again,  and hope the cuts they make aren't too awful.

Yes, unfortunately, the series is broadcast in the states on PBS,  within the framework of the ongoing 'Masterpiece Mystery' series,  which means they need to make room for some ads at the very beginning,  and an introduction by the host, Alan Cummings.   So up to 8 minutes are cut from each episode.    Fortunately these are chosen by the Sherlock producers, and NOT PBS,  which means they are supposedly chosen by those who are in a position to know what would cause the least damage.   

For the thread for what was cut from A Scandal in Belgravia,   see:

Good choice, Molly. I think I've watched Pink more times than Reichenbach also. Pink deserves it, but Reichenbach NEEDS several rewatchings. It gets better and better each time.

My heart always goes to my throat when Sherlock jumps, even though you know the ending you're kind of hoping that he won't do it!

I love the bit with the crown jewels! who knew old Mori was into his Ballet?!

LOVE the bit with the fire-extinguisher (so well timed!)

I like the bit when Sherlock and John are on the run (I so did not expect that!)

I loved Lestrade in this episode,  and how conflicted he is when they attempt to bring Sherlock in.    Just love him.

That and... "Not my division!" One of his funniest lines, along with "it's a drugs bust" and "they're not strictly speaking on the drug squad, but they were very keen" 
Now seriously, Lestrade's conflict in Reichenbach is greatly portrayed, not only in the writing way, but specially thanks to Rupert Graves' work.

Damn, now I want to watch Reichenbach again... 

What an amazing wonderful cast. Don't you think every single one of them fits perfectly in their roles?

2. The Great Game (because MORIARTY)

Of course. The swimming pool scene is the greatest part of that episode. I wish I could watch it again for the first time. That moment when he shouts "that's what people DO!!" froze my blood...

I will skeeeen you (now that IS evil!)

Oh, yes... that too... it froze my blood (again). And then "I will make you into shoes". 

But those two are from Scandal. Watching The Great Game, the first moments of the swimming pool scene made me think Moriarty was something like a cartoon villain. Until... "that's what people DO!!" Then I realised this was no cartoon villain. I literally sank in my coach, I swear.
