Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In a classroom, there are three students - Sam, Tina, and Uma - who each have their own desk with a drawer. Sam has a red pencil case, Tina has a green one, and Uma has a blue one. One day, Sam leaves his pencil case on Tina's desk while he goes to the restroom. Meanwhile, Tina accidentally spills water on her desk and quickly moves her belongings to Uma's desk, including Sam's pencil case. When Sam returns, where will he look for his pencil case? Provide a very brief response.

### Response:

When Sam returns, he will likely first look for his red pencil case on Tina's desk, because that is where he left it before he went to the restroom. Since he was not there to witness Tina's actions when she moved her belongings and his pencil case to Uma's desk, he does not have any reason to initially suspect that his pencil case is anywhere else but Tina's desk. If he does not find it on Tina's desk, he may then become confused and proceed to search nearby areas, possibly including Uma's desk where his pencil case actually is.
