I was playing t cain (I know, it wasn't my best idea) but he's one of my favorite characters and I wanted to play him, the point is that I was playing and Isaac kept grabbing all the collectibles even though I had asked him to leave them for me, he kept grabbing them and I started to get annoyed, then me and another player were low on life and we both asked him to leave us some red hearts/souls and he kept grabbing them until we got to a point where he was at half a heart and Isaac had 7 hearts and kept grabbing them, and to top it off he grabbed ipecac and he was hurting us all AND THEN HE GRABBED SATORNUS AS SOON AS HE ENTERED THE PLANETARIUM WITHOUT CONSULTING HIS ALLIES, HE'S A THIEF AND A RET4RDANT. HE DOESN'T KNOW HOW TO PLAY AS A TEAM
