One of the most iconic and memorable episodes of Smallville has arrived, so of course we had to do another video for you all (check out our YouTube!). Bart makes a surprise return in Metropoils after saving Chloe from a gunman. Clark is happy to see his lil bro bro, but he suspects he’s up to no good. Come to find out, Bart is now working with Oliver on sabotaging Lex and all of his illegal Kryptonite experiments. Oliver also reveals he recruited Arthur Curry and Victor Stone for this superhero operation, who all want Clark to join them too. Guess what Oliver also does? BREAKS LOIS’ HEART! Justin Hartley (This Is Us, The Young and the Restless) makes his final season six appearance as original DC Comics character Oliver Queen, a.k.a. Green Arrow. Kyle Gallner (Smile, Scream 5, Interrogation) returns to special guest star as original DC Comics character Bart Allen, a.k.a. Impulse.
