Alex approached Emily and whispered in her ear. "Emily what are you doing here, what about Lilitth?"
"It's alright she's back in the mansion sleeping. Also I'll be back before she even notices that I'm gone." Emily whispered back.
While Alex and Emily were whispering to each other, Evangeline and Rachel were looking at the two in envy. Rachel already understood that Emily and Alex weren't in that kind of relationship, and that they're just friends, but seeing how close she is to him... That they're able to have secrets between on another was envious.
Evangeline on the other hand was also jealous of how close Alex and Emily were, but she looks at the two differently from how Rachel does. To Evangeline Alex and Emily looked more like brother and sister, or something greater than that, it doesn't feel like they were just friends. Still it doesn't feel like they were lovers either.
