Is there any hidden meaning behind Travis and the prosthetic arm? - Woman in Black Spaghetti Strap Dress Holding White Flowers

In the last episode of Dexter season 6 (S06E12), Travis finds the prosthetic arm

that Louis sent to Dexter

He's seen wondering what it is, puzzled:

But quickly after that he put the arm back in the box when interrupted.

Since the arm isn't just "small detail" like the cereals he ate or shirt he wore while visiting Dexter's house, I am wondering if there is any meaning for this short scene, e.g. leading him to perform some actions later which he wouldn't have done otherwise?
