Sister-in-law

 ''I… You see, I came here to freshen up. I didn't expect to bump into your wife here,'' Claire said to Archer, sounding all calm and stiff. 

Elvina closed her eyes, almost manifesting a siren cardiac arrest. Came to a private suite to freshen up? Let alone Archer, even Gold would not buy something like that.

Archer did not say anything. 

After a long moment of silence, Elvina finally opened her eyes, ''How did you know I was Kate?" she asked as the man started stepping inside the suite. 

''The day when I left for the business trip. That morning, you stumbled into the VIP elevator and I grabbed your hand. It's not like I am not familiar with how your hand feels like, or your unique cold skin. I understood why you felt somewhat familiar all the time,'' Archer said.

Elvina did not know whether to blush or be upset at her stupidity. She did the former. 

Claire turned around to look at them and Elvina slowly swayed her palm.
