I loved Tom's performance in 'Splinter.'
I don't remember much about 'Solitude,' just that Martha was sick.
'Lexmas' was a good one.

This line from 'Sleeper' when Chloe's talking to Clark is so great.

"You do realize that your greatest superpower is your ability to win me over with just one look, no matter how ridiculous you sound, right?"

Gotta love how Clark can convince Chloe to help him, just by looking at her that way.
