OMG OMG OMG YESSSSSSSSSSSS!!!
Omg, those pics of Bruce and Clark doing butterfly and eskimo kisses are the best. Which bring me to a head canon. Bruce use to give butterfly kisses to his mother when he was younger and now only does it to people he loves. Eskimo kisses was a family thing, like it was their hello, so he sees Clark as family and says hello to him in his family talk.
