Why is Judy so touchy with Nick?
From the very beginning of the first film when we’re introduced to Nick at the ice cream bar we see that Judy approaches Nick and places her hand on Nicks arm as a way to perhaps convey her sympathy.
We don’t see her display this sort of affection towards any other character, especially ones she has just met with the exception of perhaps Mrs Otter-ton?
The next time we see her display physical affection towards him is at the cable car scene where after Nick has finished trauma dumping she instinctively places her hand onto nicks paw. And then after he breaks the awkwardness with his new plan she gives him a little love tap.
Throughout the remainder of the franchise we see this physical affection increase. Why is Judy so affectionate physically with Nick?
