Would Bucky consider Harley to be a suspicious person? She is definitely a character. And she is approaching Adia to answer the question.

Her general demeanor is one of concern right now. And recently, after successfully acquiring a flash, Harley has alcohol to offer. She has grabbed two Styrofoam cups from the coffee area, and places them down in front of Adia. Then she pours half of a cup for both of them (it is whiskey that is in the flask tonight).

"What happened, sweetness?" Yes, Harley has given Adia a nickname.
