It had taken Adrian several hours to fully come to grips with what had happened. The abandoned construction site. The alien. News of an invasion. At first, he wrote it off as a dream, but as he heard the others, it became apparent that it was terribly, horribly real. There'd be no waking up from this, no sudden revelation that it was all an illusion, just like in that review of "The Matrix." For a while, he dismissed the reality as being too ridiculous. A team of teenagers chosen by an alien being to have superpowers. Just like the Power Rangers, or maybe the Planeteers. 

Once the truth had set in, Adrian wrestled with the implications. The Andalite had told him that they could morph for up to 2 hours at a time without being trapped as that animal. They had to fight the Yeerks by changing into dangerous animals, hold off the invasion until Andalite reinforcements arrived, and try to survive until then. To accomplish those last two goals, cold logic dictated that they'd have to accomplish the first, and to do that, they would have to 'acquire' said animals, probably at a zoo. Even so, the odds were stacked against them. A large animal control team could put them down, even in the best case scenario. This was not a war which could be won by strength alone. 

He walked over to Emma, Stephanie, and the others. "I'm sure the others will be here soon. And yes, it happened to me too. If anyone still thinks this is a dream, it isn't. We're the Mighty Morphin' Power Rangers now, and Zordon just died in the first episode."
