So the rhino runs a train all over Kuuga, proving that transformation is, in fact, not a free action here.

Anyway, it seems the rhino is targeting trucks due to the exhaust they output. Is he fighting for the environment? I dunno. All I know is that they speak English (Japanese) for the first time (Technically second, as they spoke it a few episodes back, but it was one sentence and mimicking what the radio was saying).

The subplot involving one of Yusuke's teachers is also interesting. I'm only pointing it out because, honestly, it's the first time in the series where I felt any sort of interest. The possibility of Yusuke's former teacher quitting because Yusuke would be unable to meet up for a date planned 16 years after the fact holds the most tension out of anything else the series has offered thus far.
