He’s smarter than everyone he knows, including his teachers. So it’s no surprise tonight when Sheldon ( Iain Armitage) is offered a full scholarship to an advanced school. The only problem? It’s in Dallas, a three- hour drive from the Cooper home and worried mum Mary ( Zoe Perry). “An Eagle Feather, A String Bean, And An Eskimo” is a sincere, touching and funny episode. Sheldon is shipped off to live with a foster family and go to the new school. But soon, even those who are slightly relieved he is gone start to miss him.
