I don't think it matters who said the baby was not Clark's son. The bad guys were bound to say it as they need to play up that it is Navance's son or they will get no traction with folks in the USA.
What I am looking forward to is all the news commentators who compare photos of Clark and Christopher and point out how Chris looks just like Clark.
They will be making fun of Navance's claim and showing side by side photos.
I expect some enterprising media type will get baby pictures of Clark to post side by side with Chris's photo.
I rather expect Martha will be showing off those baby Clark photos to everyone.
For several days Clark will have it rammed into him that Chris
IS his son.
At some point someone is going to be wearing a bit of Kryptonite jewelry near Lois and Chris and Lois is going to have proof positive.
Also one can get a swab of Clark's DNA from his mouth no need to break the skin. So I bet some reporter will will grab a dirty glass or tissue and then one of Chris's dirty diapers and run the samples.
So Clark will be confronted with
- Photos,
- DNA and
- Kryptonite.
