"Who could it be?" She observed his expressions but then her eyes went to the spilling coffee behind him. "Oh no!" She jumped off the counter immediately and started cleaning up the mess while he went out.

"What am I doing here? What are you doing here?!" Delilah pressed the word 'you' and pushed him aside, stepping inside the apartment. 

"Where is…Oh! There you are!" She crossed her arms as Isabella walked out of the kitchen, her eyes lingering in between Xavier and Delilah. 

Delilah's eyes caught sight of the mark on Isabella's neck which wasn't visible before since she came here. It appeared more reddish then silver suggesting that blood was freshly sucked out of it. Upon watching that it didn't take her much time to confirm her suspicion.
