"Oh?" Brow quirking up, Marguerite smiled, "That is definitely something exciting." What could she say, the actress was a romantic at heart. Plus she was very much 'live each moment like your last', even before the whole death thing. So to hear about a friend with a new romance? Why wouldn't she be happy for John?
As for why he was staying there? She nodded.
"That makes sense. It can help having someone there when you wake up..." But she did notice the use of the term when. So either he was just deciding he was going to keep dreaming and it wasn't his actual end, had realized that there was a feeling to finality that he had not experienced or....just hoping. It was hard to say.
