Thane's heart nearly comes to a stop when she looked up in excitement and smiled at him. He's pretty sure she said something about liking it and thank you but he couldn't really hear anything over his own heartbeat.
Her smile was breathtakingly beautiful... and the same exact one in the picture. He swallows hard and forces himself to look down and eat his soup. He couldn't even taste the thing! All he could see, hear, and focus on was her.
Seeing how she and Cruz interacted, he became suspicious of him knowing the truth about her but after seeing their reaction, it was clear to him that Cruz knew about her secret. It sent him into an unholy rage knowing the bastard was hanging that over her at times to make her submit.
