Lucas was definitely eavesdropping XD he's so quick to save Athy. He's probably also jealous :v Lucas knows more about Athy than she probably does about herself and that's why they work for me. Athy gets to be who she is in front of Lucas and so does Lucas in front of her. They're both have to be proper in front of others so if you think about it they are each other's best friends. Athy would probably deny that though since Lucas always teases her but I think on some level, she knows he's always there for her.
