Holy mother fucking bastard!
Arianna swore mentally when her eyes fell on Elijah coming in her direction, with a woman by his side whom she surmised to be Marcel's cousin.
When Marcel told her his cousin and the mysterious guest were coming over, she never heard the name "Elijah" being mentioned, so what then was he doing there?
It was a good thing that Arianna was smart and was able to figure out that Elijah was working undercover in Marcel's gang. Hence, she quickly masked her expression knowing that Marcel doesn't trust her anymore and currently has his observant eyes on her.
Showing shock was a straight giveaway to Elijah's identity and all of her efforts to protect him would be nothing because Marcel would end him right there and now.
For once, Arianna was thankful she had been around her dramatic cousin Claudia and was able to pick on a lot of acting skills - yep, the girl was cray cray.
