Ava didn't know the kind of response to give a child like Sophie, thus, she glared at Hendrix, begging him to at least say something on her behalf that would be super important and she knows about it so well.
Hendrix knew what the pleading look on Ava's face signifies, that he should help her. Well, he didn't want to talk too much, he just helped her by saying the essential things as that was super important and she totally knows about this.
The feeling that overwhelms Ava is when he heard Hendrix's silk voice flow through his ears. It was amazing, priceless, and she which he could keep on talking kike a tuned radio.
"For as long as your Aunt Ava wants you to stay, baby girl. My home will always be open for you, and that means you are welcome at any time of the day, week, or ever," he said in a weeny tone, making sure that his message is being passed in one piece.
