Help deciding if i should go to court.?

My friend and I went saran-wrapping a couple of friends cars and we got caught by the police. My friend was drinking and it was his idea. I only went along cause i did not want him driving. I got caught also, he ran then decided to come out. He got underage drinking and disorderly conduct, I only got disorderly conduct. Now I am stuck...If I go to court and get my ticket removed, I will feel as though I am backing out on my friend and leaving him the only one to blame. I dont know what to do. also if I dont go and find out he does for the DC, then what if he gets it taken away. If he doesnt go should I not go???? I am stuck. Thanks for the help in advance!
