He accompanied Roland, Alain and Cuthbert for some time after they returned from their first adventure back to Gilead. Although Sheemie is not seen for some time, it is known that Sheemie will play a big role in the events to come in the Dark Tower series. Mainly because of his gift, the Touch. Even the Crimson King had interest in Sheemie, but he managed to repel the Crimson King's influence.

In the two part Marvel series Sheemie's Tale, Sheemie relates the events of his life which took place between the novels Wizard and Glass and The Dark Tower, explaining how he was taken to Algul Siendo by Randall Flagg and made to use his substantial powers to help erode the Beams as one of the Breakers.
The Dark Tower IV: Wizard and Glass
Roland, Eddie, Susannah, Jake, and Jake’s pet bumbler survive Blaine the Mono’s final crash, only to find themselves stranded in an alternate version of Topeka, Kansas, one that has been ravaged by the superflu virus. While following the deserted I-70 toward a distant glass palace, they hear the atonal squalling of a thinny, a place where the fabric of existence has almost entirely worn away. While camping near the edge of the thinny, Roland tells his ka-tet a story about another thinny, one that he encountered when he was little more than a boy. Over the course of one long magical night, Roland transports us to the Mid-World of long-ago and a seaside town called Hambry, where Roland fell in love with a girl named Susan Delgado, and where he and his old tet-mates Alain and Cuthbert battled the forces of John Farson, the harrier who—with a little help from a seeing sphere called Maerlyn’s Grapefruit—ignited Mid-World’s final war.
The Dark Tower VII
At the outset of the final installment of our saga, Roland’s ka-tet is scattered across several different wheres and whens. Susannah Dean (still in the clutches of the demon Mia) is in End-World’s Fedic Dogan: a chamber of horrors where magic and technology can be merged and where a monstrous half-human child can be brought forth into the world. Eddie Dean and Roland Deschain are in Maine, 1977, searching for the site of otherworldly walk-in activity, and a possible doorway back to Mid-World. Jake Chambers, Father Callahan, and the bumbler Oy are battling vampires and low men in New York’s Dixie Pig Restaurant, circa 1999, a place where long pig is definitely on the menu. As soon as our tet reunites, they must journey to the headquarters of Thunderclap’s Wolves in order to discover exactly why the Crimson King’s minions have been culling the brains of young children for twin-telepathy enzymes. The answer is more horrible than they realized, and bears directly upon Roland’s quest to reach the Dark Tower.
