What happend if i go out of a hidering? do i go half? so i step 1 instead of 2?

I roll a 6 and i have a few figures on hidering this matter to the squares and the number? or i just need to count the squares at the end?

1. Sidestep locks the speed value at 2 and therefore you can move up to 2 squares even if you start in hindering.

2. You just count the squares moved. Hindering terrain will not have any effect on the number of squares that can be moved. However a character that moves into hindering during this move is still forced to stop unless it can ignore the hindering terrain for movement purposes.
