This was a week of fussing over the phone. Cherry saw a news item reporting the train explosion that Mark and Happy witnessed during their forced layover at a train terminal, so she called Mark and tried to force Mark (and Happy, who never really factored into Cherry’s worries, but we’ll assume the best) to come home. Mark spent the week dodging details, claiming he was fine, and pushed his inherent need to “get to the bottom” of the incident and make sure everybody knew what was going on.
I don’t know how long a day is in the Trailverse, but it must be about 30 hours or so. They were already halfway through the day when the explosion occurred. Then they were in a hotel ready to call it day when they went to visit Rex Scorpius (exactly how they got there is unknown, unless they called an Uber or rented a car), who told them what he knew about the train incident. Then back they go to the hotel, to spend time talking with Cherry. Heck of a day.

Mark is sporting a nice beach shirt, rather than his out-of-place red-check flannel. Today’s nature lesson is informative (at least to me!), despite the opening and closing puns. Even they are not as abrasive as past puns.
