The telepathy tests have hinted towards a common consciousness (Ep. 2 iirc), due to the way thoughts appear to enter the minds of child and mother instantaneously. There are plenty of other lines of enquiry that hint towards this idea of a collective consciousness too. There's a lot to take and the only way my line of thinking will make sense to anyone is if we deal with each of these topics one at a time. And it will take time.
With that in mind, the topic of remote viewing would be the logical next step. But I don't think we're done yet on telepathy.
