Usually they have a toast or something to the next step of the show.
I'm sure a lot was edited out so that they could have enough time to show her long goodbye to Graham.
Can you imagine being the other guys during all this? If the speculation over at ABC.com was rue, that there was a pre-cocktail get together and Deanna & Graham had an argument then, the other guys would have had to know what was going on. Especially if Graham was suddenly changing clothes & leaving.
In some ways, Deanna & Graham act like an old couple with a lot of history & drama between them.

You can always tell when a couple have had a row, even when they don't say anything to anyone else.
Then to be waiting inside while she said a looong, tearful good-bye to Graham. Her mood couldn't have been all that great when she went back in for a toast. I want to know what
they are thinking during this.
Are they so naive as to think, "Well, they always argued, so good, he's out of the way now? She wants a nice, calm relationship" Or can't they see, "NO, she never has had feelings for you in the same way that would make her so angry, fight, and
still want to keep the guy around."
If she fought with any of them over a little thing, they'd be history, without any tears on her part.
Deanna wants to feel she's in love, she will even beg and take the drama to get it, as shown in her begging both Brad & Graham to please change to be what she needs, love her and give them a chance.
When I heard her say,
"On paper Jeremy is perfect..." I knew that was the kiss of death for him. No one says, "On paper." If they
feel something, they say, "He IS the perfect one!"
