I urgently need your HELP!

Ok so I guy I know named Mark got in a fight a few months cách đây in a club and his good friend alex saw the whole thing. Alex has to be in court this week but he cant go due to work issue's. Now Mark is calling him a coward and saying they will no longer be friends. I dont know what to do but alex would be there if could. He is a really nice sweet guy.. What do bạn guys think?
