Deep in the unconscious, hes remembered, and theres a little acorn placed in there, says Gabel.
This is what ultimately leads to Walters inventions for normal people,like The U-Dog.
Walter hopes these gadgets will endear himself to Paige, but that definitely wont be the case.
I think shes less than impressed, says McPhee.
I think everyone seems to think theyre kind of stupid inventions.
Looking ahead, Paige will continue to pursue a relationship with Tim Armstrong (Scott Porter).
Im excited for Walter and Tim to sort of befriend each other, says McPhee.
However, it wont be completely smooth sailing.
Its a volatile relationship, teases McPhee.
Paige gets irritated by the fact that the team wants to be involved.
