Imagine
You are currently with Bailey on tour and are hanging out with him backstage before his set. He shows you some of the new tricks that he's taught Marley (including the one in the picture). You guys continue to play with Marley till Bailey has to go on stage. You end up continuing to play with her as a way of trying to keep her occupied while Bailey is on stage, so she doesn't try to join him on stage or get lonely and feel some separation anxiety from seeing him on stage and not being able to join him.
