Clark gets infected with silver kryptonite and becomes delusional and paranoid. An interesting episode for exploring Clark’s deepest fears and the fascinating character of Milton Fine. 8.5/10
Martha grows gravely ill with a Kryptonian virus – it seems Jor-El has come to take a life, just as he promised. A thrilling arc-heavy episode in which Fine’s evil plan comes to fruition. 8.5/10
Lex gets shot and has reverse-A Wonderful Life vision of a perfect life. Michael Rosenbaum is excellent here. Less good is the very silly subplot with Clark meeting the real (?!) Santa. 8.5/10
Lex’s student campaign team get a bit too overenthusiastic in stopping Jonathan Kent in the run-up to the election for state senator. Meanwhile, Clark and Lana’s relationships hits a snag.
The main plot – Panic Room at the Luthor mansion – is OK, but it’s particularly interesting due to how it pushes Lana and Lex together. Will this finally force Clark to tell Lana the truth? 8/10
What a 100th episode this was! Lots of callbacks to the Christopher Reeve movies, time warps, romance, fake-outs and a big emotional death. The show surely won’t be the same again. 10/10
