Warning: MAJOR SPOILERS from the Superman & Lois series finale.Jordan Kent actor Alex Garfin, takes ScreenRant behind the makings of the Superman & Lois series finale and bids farewell to his DC role of Superboy. In 2006, after merging UPN and The WB into one network, The CW began its DC TV era with the Superman prequel show Smallville, featuring Tom Welling as a young Man of Steel discovering his Kryptonian heritage. With the changes behind The CW under Nexstar, it was only fitting that a different Superman series brought the superhero genre to an end on the network, with Superman & Lois season 4.
