There was probably little security could do to stop him going anywhere, you try catching someone who is faster than... well a lot of things and it's taking him some concentration to stay on board. Not phase through things accidentally. The ship is something new to explore and wow he is he going to check everywhere. Places he's meant to be or not.

When he finally settles, it's of course where there is food. He does like to eat. All that moving quickly burns a lot of energy and he has to keep up. So, there are a lot of different things on plates, the whole table is full of food and if you blink it's gone only to be replaced with more, somehow.
