Cerebral to a fault, Sheldon (Iain Armitage) has a challenging time as his body and hormones really put him through the wringer when puberty starts to kick in, in the Season 5 finale, "A Clogged Pore, a Little Spanish and the Future." As Mary and George Sr. (Zoe Perry, Lance Barber) both search for new jobs, Georgie and Meemaw (Montana Jordan, Annie Potts) quietly take a business trip across the border. Raegan Revord also stars.
