Bible blooper?

Mark was there.He was not a disciple ,but a teen following the group.When the Jewish guard came to arrest them,they tried to grab Mark but he spun away and they tore his tunic off and he fled in his gird(Jockey Shorts).See Mark 15 & 16.There was also always agroup of Disciples around them who were not the "inner circle "of 12,Jesus usually traveled with 50 or 60 people around,including,the women.I'm not upset,it's just that people love to jump before studying ALL the scripture.
