Cassidy is still hugging Hugo and patting Joshua on the head when she notices the look that Asher is giving her the whole time.
He appears to be not pleased, which she guesses is because of what they have agreed on back then. She made a promise that she would not be in contact with any member of the Millicent family - something she swore more to herself than to anyone else. He was the one who helped her get out of their radar, and he made sure that she would never be bothered again.
At that time, Cassidy was only desperate to move on and start anew. For that, she had disregarded even the good things she left behind, including these nephews of hers who have held her dear.
'He's probably thinking that I've kept this a secret from him. In reality, I've just reunited with them today. How distrustful of you, Asher...' Cassidy brooded and sighed, wondering how overprotective he could be.
