Forefend and Throws

[Cheese]

With Heimdalls Forefend ability, what exactly is the timing window to use it in regards to throws. Say for instance Heimdall has a character thrown into him. Does the sequence go:

Move thrown character, roll dodge dice, Heimdall makes Forefend attack. 

Or does he make his attack before rolling dodge dice? 

[Thoras]

If a collision occurs, resolving the collision occurs prior to rules that trigger off the end of the movement.

You will roll any dodge dice and resolve all rules based off those interactions before Heimdall can use forfend.
