Accomplice in murder

Back in the penthouse, Ari watched Nicolai stuff Mrs Harlow's body inside a trash bag, which was then placed inside a large carry bag. 

She turned her head away, not being able to look at the sight in front of her. It was her fault that Nicolai had to grow through this trouble. 

"Will everything be alright?" This was her first time killing someone, and Ari couldn't help but worry that something might go wrong. 

"Everything will be alright," Nicolai replied just as Kayden wiped the floor clean with water first followed by a solvent that wiped the traces of blood making it impossible for it to appear under the blue light or any other tests.
