I am upset by this myself, but I know that something will happen for them to see each other again and have some sort of reconciliation.  Sherlock Holmes and John Watson are meant to stay together.

I think this has to do with John's shock from losing his wife so suddenly and in such a way and his mourning.  Sherlock promised to keep him, Mary, and the baby safe, but he failed.  But that was because Mary wanted to protect Sherlock.  I think she saw what was happening and couldn't let him be shot again.  John was not counting on Mary having her own agenda of also protecting the people who matter to her, which include Sherlock (she couldn't let history repeat itself with Sherlock getting shot, or John losing Sherlock again). 

And I think there's a bit of hypocrisy on John's part, which can happen since people are contradictory.  John said to Mary that they should have discussed things together.  But John isn't willing to speak to Sherlock about what happened.  I know it's a bit different, but that's something I thought about. 

But at the same time, he doesn't want to completely cut himself off from Sherlock.  He did give Molly a note to give him, after all.  He may be putting up a front of not wanting to see him, but I think part of him doesn't want to completely break things off.

I would've understood it better if John had been there the whole time so that he saw what really happened. It would than make sense if he had yelled something like "Why can you never shut up?" Not saying it would be right or Sherlock's fault, but that would've been a reaction I could understand.

But to be angry to the point of not wanting to see him because of the vow? I don't get that.

Yeah this doesn't make sense for me either, the woman was obviously connected to Mary's past and for all John knows she could have just shot at Mary and there was nothing anybody could have done about it.

The only thing I can think of (unless his actions are in some way part of some big plan to push Sherlock for some reason) is that John can't deal with both the pain of losing Mary and his guilt about his infidelity and about sending Mary there first at once so he is putting all of his guilt and anger at the situation onto the closet person to him, Sherlock. I think he will come to realise it was not Sherlock's fault.

This does make sense in a way. The pain and guilt becomes too much and so he lashes out towards the one person who is the easiest target for him - Sherlock. That could be an understandable (although of course not right) action in a wild moment of shocking grief.

But I don't see why he would continue with that anger even when he got back home and had time to think things over a bit.

I am sure there will be a reconciliation. And this time, I hope John gives Sherlock a proper apology. 

I hope there is a proper apology, too.  And I think there is a combination of grief and guilt that's making him act this way, even though it's not right.

From the first trailer, we do see Sherlock and John together in the car, when Sherlock talks with Culverton Smith. I gather that is the second episode? So there will be some form of communication and working together(-ish?) next episode, at least.

I think we forget sometimes that grief and perhaps a little bit of guilt for a flirtations/affair can make a person lash out no matter how illogical. We've seen previews and we know they'll be working together again so I am sure the friendship will mend once John gets over the initial shock and grief of losing his wife. We all have moments when we get a little irrational when hit by intense emotions I think. 

I think he's being very unfair to Sherlock but I understand why and I know it will work itself out. 

I'm more upset that John was cheating on Mary. Something I didn't expect from him but perhaps it's some pent up passive/aggressive issue about how she deceived him in the beginning. A lot of psychological issues going on here for everyone. 

Well they are both in the ep 2 trailer!

It's irrational and unfair, but I think it's kind of tied to the Samarra story, and John's faith in Sherlock.   He'd already seen Sherlock go to extreme lengths to protect Mary, so believed he could keep her safe.   He believed him that the risk was abroad, where they went and she saw death (having a gun pointed at her).  Sherlock convinced her to come back to London, promising that she'd be safe, not realising that London was Samarra.  They almost misled us too, I think, with that exotic location.   Sherlock basically led her back to her death, after promising to protect her. 

I also think there's guilt there - guilt over bus stop lady, and guilt over sending Mary to meet Sherlock, when Sherlock had specifically asked for John to come, not Mary.  Although I don't know if John ever saw Mary's text. 

John didn't see Mary choosing to die, but I don't know if it changes things ... he might still have been angry that Sherlock put her in that position. 

I do think a lot of it comes down to extreme emotions when dealing with grief. 

I agree, Pops, on both your points.  Also, I forgot to mention before: I really like the picture in your signature!
