I kind of got the impression that the spirit could only transfer by touch, once it had possessed Martha in the first place. At least all subsequent transfers involved touching.Morrus said:How does expelling the spirit from Clark's body solve anything? We've already seen the spirit can possess anyone - that's how it got Martha in the first place. It'll just go find someone else. Plus, it knows all about Clark, his powers, Kryptonite, etc.
