Yeah, okay. This is a bit weird. I wasn’t aware that lions (or cubs) could show distinct emotions, such as sadness or fear (as in panel 3). They do seem to have some limited facial expressions, from what I could find out, but most of them appear to consist largely of big, open mouths that say “I’m coming to eat you!”
Seems to me that Tess is using her “therapy” more to project her own feelings of loneliness onto Rex. Mark has a point, though, but I’m not ready to call in the ASPCA until we find out about the parents of these cubs and where they sleep.
Just a thought: You think this might wind up like the original Jurassic Park, after the dinosaurs escape?
