Lawrence first appeared on Boy Meets World's fifth season as Shawn Hunter's (Rider Strong) long-lost brother and Eric's (Will Friedle) roommate. When we last saw him, he was taking his 6-percent body fat to the Peace Corps with his ex-girlfriend Rachel (Maitland Ward).
This is only the latest Boy Meets World reunion the spin-off has staged. Girl Meets World has also featured the returns of Strong, Friedle, William Daniels, Anthony Tyler Quinn, Trina McGee and Blake Clark.
