I was driving in my car and thinking if she isn't Tek's wife or daughter, could she be his sister?
Ard is a definite mystery. I hope we get more clues about her soon.

I was also thinking that the childish pictures don't necessarily mean that a child drew them. If Ard was 4-5 years old when they left Krypton, these may be pictures drawn from a memory of the pictures she drew as a child.

I still maintain that there is nothing nefarious about Tek's visit. Colorful representations of a happier time could draw many of the New Kryptonians to her door.
