While on the roof of the barn, Jonathan is contacted though the octagonal key and Clark saves him from a fall. Clark goes to the Kawatche caves with the key trying to find an explanation for what happened, when Lionel Luthor unexpectedly appears and expresses his suspicion towards Clark. Lionel goes to New York and secretly meets with Dr. Virgil Swann and proposes an association to investigate Clark. Meanwhile, the FBI is revealed to have bugs in Lex's mansion for a surveillance to obtain evidence against Lionel, and Clark becomes a suspect due to the interest of Lionel in the apparently simple "farm boy". Later, agents, led by Frank Loder, arrive at the Kent farm to search it for the missing octagonal key, leading Clark to mistakenly believe that Dr. Swann betrayed him to Lionel. Meanwhile, Lana cannot seem to make up her mind whether she wants to stay with Clark or not. Written by Claudio Carvalho, Rio de Janeiro, Brazil

3x17 - Rewatch (Luthor-Clark-centric)
21 July 2016 | by (United Kingdom) – See all my reviews

You know, I really hate how they make Jor-El seem like a terrible father. He sent his son to earth to save him for goodness sake... that is enough in my book for me to love Jor-El. Plus, Russell Crowe plays that character so I have a whole new level of bias for Jor-El.

Lionel Luthor finds Clark in the cave & tells Lex that they need to get to the bottom of the Clark Kent mystery.

Throughout all of season 3, Lex has really been trying to protect Clark, Chloe & Lana. Give that man some love & some friends.

Clark's stupidity is getting unreal. The dude is always zooming away & expecting everyone to turn a blind eye at his sudden disappearance. Also, the way he accuses & attacks Lex is low-key pissing me off. He is on some Barry Allen-type (The Flash TV show) shite.

Clark & Lana share a kiss. Well, that just open an unhealthy can of worms. Smh. These people have got to stop with this relationship. It is toxic & unhealthy AF. Also, the way Lana went to Lex about Clark... she might as well get with Lex.

I am ready for this season to be over because I am so damn tired of Clark & Lana, the caves & the Kents. I am over here preparing myself for season 4 when Queen Lois Lane makes her presence known.
