Divisive Thicket

How do you get pass the hole in Divisive Thicket, and how do you get back to Tor from Halaina, stuck with nowhere else to go.

I don't know what you mean with the hole in Divisive Thicket, but from Halaina to Tor:
Leave Halaina through the south exit, walk over to the port (south-west from the city), take the boat to Tor.

I tried that and it won,t let me on the ship, and the divisive thicket is up from Halaina and there no where to go but to left and you fall in a hole and into a cave.Thanks

Ingrid will have to collect the blue flower to the left of the grassy spot where you fall in. It's for a potion and she'll walk across without any problem. Something to do with tears, I believe. You have to wait until she knows to collect it.
