Perhaps with longer exposure she would have realized that Barry wasn't exactly acting as Clark did. She was a bit distracted with 'Clark' coming back to life and all.
Exactly...Lois isn't really isn't analyzing things too closely. She grieved her way through a sleepless night, and now is overwhelmed with joy that Clark's alive. She's just running with her emotions. Kissing is an art form - it take practice to perfect it. Barry has had a lot of practice in the past year.
I have full faith and confidence that, with just a bit of practice, Lois will rate Clark's kisses even higher on the scale.
But that story would appear on the other side of the boards!
I'm glad you all liked Barry and Clois...everyone deserves a happy ending!
