What can I do in Evan's room?

Not much you can interact with at first glance. There is that alarm clock.

Where have you last seen a clock around here?

Note the time the poker clock is permanently set at, and try it on the alarm clock.

Tap each hand and then tap where you want it to be. Use the hands to point at 1:10.

You now have access to a keypad. But what could the code be?

The clue is again at the poker table.

Remember the hand that lady was holding up?

Look again at the manifest to get the Snowman room number.

Input 3009 and turn around to access Evan's travel case.

Tap the panels until one opens to reveal a useful tool.
