Dean's smile widened even further when Ritchie said he would sing again, this made him rather happy. He then watched Ritchie as he put the cup deep into the trash can, tilting his head to the side as he didn't understand as to why he did that, but he wouldn't ask as it wasn't really his business.
"Good luck, Ritchie!" He gave him a wave and waited for hear him sing.
