Don’t You Hate When This Happens?

Dick Grayson has always been good with exotic megafauna or, in other words, circus animals. That was clear in his first visit back to a circus in Batman, #2, when he hitched a ride on an elephant while looking for an escaped giant. More recent comics and cartoons have made much of his relationship with the Haly Circus elephants Elinore and Zitka. So I have to believe this lion is just enthusiastically showing affection.
