Someone still has yet to theorize about the demarcation of the Lois & Clark relationship using The Cut, assuming that The Cut was done for just practical or aesthetic reasons.
If I recall, the first cut was done because Teri wanted a change (and it didn't sit too well with the producers since she didn't consult them), but the second cut, the one that resulted in her super-short, red hair was done for her role in "Since You've Been Gone."
