In this context, Karla is using a nonverbal method of probing. Probing is aimed at continuing a discussion or inquiring closely about an area of interest, probing can be done verbally with the use of direct questioning to elicit response from a subject or with the use of nonverbal methods such as signs like, the raising of an eyebrow or the tilting of the head and other communicative signs.
