Lie appears using his time-stopping camera. He brings Hook with him as she will be vital for your upcoming Santa duties.
Hook, as it is painfully obvious, has the ability to pull things to her from anywhere in the universe. She does this using a hook, one you might find being used on a poor comedy act. You need her to bring your computer to you, you don't know where it is, but as it is an item, Hook can bring the item to you.
Of course, Lie could also bring the item to you, just as, if not faster, but redundancy is the way of the Multiverse. It's why every separate universe has several rules that just say the same thing.
