In the first episode he was seen on the drums. When the kids separate into segments, he's usually seen with Suzie, Anne, and Tom, but at one point he joined Nancy and several times he's been seen with Flip. Once when the middle kids paired off he went with Suzie, he cares for Anne and is always there for her when she needs him.
