[She's got it exactly right; in a way it's harder with Jack, since he knows exactly how personally he must be taking this, all the centuries of baggage he has when it comes to life and death. He always has this stupid, futile instinct to protect him even though he knows there's no one in the world who needs protecting less. But that includes trying not to panic about this in front of him. Jack knows he's hurt and he's always going to be there for him but a part of him still can't stand the thought of scaring him by letting him see this. Not that he was planning on dumping it all on Chuck, but it's happened and it's too late to be embarrassed about it. He likes to hope she gets at least a part of it, having died herself.
Eventually he quiets down but stays where he is for the moment, apologizing softly.] Sorry. And sorry I broke your plant.
