I didn't like the funeral either....I was also suprised about how many people attended and it ended up seeming like it wasn't really even about Robin, but about the people around her.
Now it makes sense what John was illuding to Sam when he said that "maybe they knew eachother in another life..." I didn't watch the night time soap so I was out of the loop.
Also, I am a couple of days behind, but do you really think Jason would be so cruel to Sam knowing that she's preggo and has been under so much stress?? Even though he doesn't like decisions being made for him, I think he would understand why she felt like she needed to shelter him for a bit. I just didn't think the writing was very believeable in my opinion.
