Against every instinct she had, Buffy did indeed take Fred's advice and stayed what she figured was a safe enough distance away from the Wolfram and Hart building in hopes that she wouldn't further jeopardize her sister. If Dawn was going to die at anyone's hand that night it would be Buffy's for doing such a stupid thing.
The building itself showed no signs of any duress occurring within it, which led Buffy to hope that either Dawn had changed her mind and gone back to the hotel, or she and Connor had safely done what they came there to do and left just as quickly. Then of course there was the alternate, more terrifying thought that perhaps the two of them hadn't even gotten that far. Perhaps they had already been captured in their attempt. Or worse...
No, Buffy would not allow herself to think like that. She would watch the building, but until she saw something that led her to believe her sister was in grave danger, she wouldn't barge in and give her away. Besides, she was with Connor. He could protect her. Angel had all but assured it.
Time seemed to crawl by without a single outward clue as to what was going on inside. It wasn't until Buffy spotted some very small figures moving rapidly away from the side of the building that she decided to act. She followed at a safe distance, hoping that if it was Connor and Dawn they were safely moving away after a job well done and were not being followed.
She tracked them at a distance until they stopped underneath a bridge to catch their breath. It was then she noticed that one of them was indeed injured, however it was not Dawn. It was Connor and he looked to Buffy to be quite upset with Dawn. She couldn't hear what they were saying, but she knew whatever it was, it wasn't 'good job now let's go get some ice cream'.
She was about to step closer and try to mediate the argument when surprisingly she watched Connor kiss Dawn. Dawn looked equally as surprised but nevertheless returned the kiss. Buffy found herself gritting her teeth, her insides knotting together. She couldn't explain it, but there was something about Connor and Dawn's mutual attraction to one another that bothered Buffy a great deal. She didn't want to see them together. Didn't like seeing them together and more than anything wanted to step forward and order them to cease and end the kiss, yet knew she had no valid reason to do so right now.
Connor ironically was the first one to end the kiss, and although she couldn't hear what they were saying, she got the sense that he was a little unsettled about his own actions. Buffy felt slightly better at seeing the boy suffer. When the two of them began to head back towards the hotel, Buffy figured the best thing to do now was to beat them to it. She was still furious at Dawn for running off the way she had, but bursting in on their little scene like this and creating another one did not seem like a sensible plan, especially not when there was still a chance that the two of them were in danger.
Turning away from them, she decided to take a short cut and to call Gunn and let him know that patrolling was probably a waste of his time now that Connor and Dawn had seemingly been successful in their mission. She would leave it up to Gunn to pass the message along to Angel and Cordelia, as she had no particular wish to come face to face with either of them right now.
