You count to the end of this interpolation-way (there are 4 nodes in, 1 is the start and 1 is the end, so 2 in between) and substract this number (2) from the last char (c). Following your assumptions from above this should work (when you can add 1 to go to the next char, you can also subtract 1 to go to the previous). This way you'll first get b and then a - those are the chars for your houses.
