In a magical forest, there is a tree that has a spell cast upon it which makes any object passing through its shadow instantly teleport to the other side of the tree, maintaining their direction and velocity. Keoni and Leila are playing hide and seek. Keoni, who is it, closes his eyes near the tree while Leila hides. When Keoni opens his eyes and starts searching, he walks around the tree but never enters its shadow. Could Keoni see Leila if she decided to hide directly behind the tree? Respond very briefly.
Since any object passing through the shadow of the tree is instantly teleported to the other side, maintaining their direction and velocity, Leila's decision to hide directly behind the tree would mean she's standing still, not attempting to pass through the shadow. Therefore, she would not be teleported, as the spell works on objects in motion through the shadow. Keoni, while walking around the tree but not through its shadow, would have a line of sight interrupted by the tree's trunk itself since he does not interact with the teleportation ability of the tree's shadow. Thus, as long as he circumvents the shadow and Leila remains perfectly still behind the tree, Keoni would not be able to see her simply because his line of sight does not penetrate the solid tree trunk.
