Go to Velma's room.

I looked out the door to make sure the coast was clear, then ran across the hall to Velma's room. I knocked on the door but there was no response. Then I heard someone coming up the staircase so I opened Velma's door and barged in.

I sounded like she was in the shower. Looks like she had the same idea I did. Her clothes were on the bed, and her case was there, unpacked. No sign of my case though.
