When Leo tells Donald he's ready (to be a mentor), Adam stands with arms folded in one camera angle, and with hands on hips in the next.
No explanation given for Donald's academy being built overnight. If not built overnight, no explanation given for where the more than forty bionic ex-soldiers were kept till it was finished. No explanation given toward the masterful team of expert engineers needed to slap out the design for this floating school and build it out in the middle of the ocean (far from material resources).
The nature of Donald's bionic academy is ill-defined and inconsistent. He calls it a floating academy, yet Leo cracks its foundation. "Foundation" is defined as the lowest load-bearing part of a building, typically below ground level. If the school truly floats, it, by this definition, doesn't have a foundation.
The hydro-loop (a shuttle tube running between the mid-Atlantic floating island and the mainland) would need a solid, fixed foundation to keep it from breaking due to structural fatigue from constant oceanic motion (especially at its connections to a truly floating island); yet, it is shown to run straight along the ocean surface. This would also put it in perpetual danger of destruction from vessels traveling along shipping lanes.
