Mark Trail: Peeping Tom

Mark’s overly suspicious mind turns him into a peeping tom, invading Rex’s privacy. Mark is making a lot of assumptions on virtually no evidence, while ignoring the actual evidence given him (that is, Rex’s desire to retire early to get enough sleep for an early morning gym visit).

For example, why does Mark seem to think that Rex snuck off to do something secretive, when Rex exited in full view of the crew, while also snubbing Mark’s overtures? And what business is it of Mark’s, anyway?

Wait. How can Rex call his dog on the phone? Is there a human taking care of Buzz who can answer the phone? Or is Buzz a modern-day Lassie, capable of understanding humans and performing human actions?
