The resistance was implied, further it was not a detail of substance because before MewTom here (no disrespect it's just how my brain ids him) the only psychic around was Forest and there was no way she'd go digging around in the other characters heads with asking.
you ask me to be clear, I try no less than three times to spell it out and each time I'm given the business in one form or another.
I'm spelling it out before our other resident psychic tries to use his powers.
in short it works as such
surface (still guarded as all strong wills are but can be snaked out)
Warning sign (neon, you can't miss it) to turn back
mindscape, (you enter here being made to find your way out or face the many dangers is the consequences of pushing that far into the person)
also Mordred, Daiki, well ugh, just warning you now Satoshi will be angry. Like unbelievably mad because of the sword
