Cracked my head figuring this one out, until I remembered the origin of his Vespa.
Aside from being his dream, it gave him a way to have more contact with Blinky, thus returning Jim what he had lost: A father figure.
That Vespa meant more than a dream came true. It was the best gift he had had since…well…since his father left.
As a single-parent child, I get the struggle and the heartache that means not having that support, not only for you, but for the parent that’s left in charge of all. When you get that aid from someone that doesn’t have the responsability, but the love to do it anyway, it means more than anything.
I love Blinky and his role as Jim’s father figure.
