Let’s not go leaping to conclusions. It’s not Lois and Clark on top of the Eiffel tower. It’s Lois and Superman. Wouldn’t be the first time the man in blue has shown Lois Lane a night on the town without her knowing about Clark Kent.

We don’t know for certain it’s the Kryptonite talking. That’s a HUGE chunk. Anything could be in there, such as the Eradicator. Or Brainiac. Versions of both come from Krypton.
