Well, the second thing is pretty logical, if a Triforian owns a power source, i.e. a power staff. There's your connection. That's what I've been saying in this thread the entire time! Like it was stated many times before, unifying Triforians can be sometimes a really painful process. And when they're joined they are joined together. But that doesn't mean that they need to have Ranger Powers to be united. They don't need to be morphed when unified.

Third thing - exactly. Kimberly IS A HUMAN. Trey IS A TRIFORIAN.

Humans = able to morph even when sick.
Triforians = when split into three beings, they're unable control any their powers (not necessarily Ranger powers), therefore, they can't do anything supernatural (except separating).
