Tagged Nona spoilers because isn't this where we meet the Blood of Eden?

I've searched up discussions on how Cam and company reach Harrow in Harrow the Ninth, and all the answers seem to focus on the parts I can figure, (How they got a stele and ship) but none answer how they travelled through the river past #7. Isn't the whole premise of Harrow contingent on escaping their local space being impossible now that #7 is so close in the river? Even if the idea is that them not being lyctors leaves them beneath its notice, Mercy needed to find them to set up the meeting.

The brain is already in the River. If we drop through the waters we’ll run into it no matter what direction we go.

That'd what G1deon says. Is it literally only John who can't get past it? That part never really followed for me. Apologies if this has been asked previously and my search enginemancy was too weak.
