With this small story, Diana shocked the entire room. She always kept her past hidden away. Only a select few truly knew who she really was, and most of them were dead. Even Christian was hearing this for the first time.
The rest of the day was predominantly uneventful. Diana helped Christian to get back on his feet, taking a few tentative steps. She had to make sure that he could at least walk slightly before they left. Charlie and Jack kept an ear out on the street, to warn Diana if anything seemed out of sorts. Vicki was left to assist either pair if needed.

Does it mean "to listen carefully about the things that are going on on the street. (any confidential information, anything that might do harm, etc.)?
