Two 3-Way Switches and One 4-Way Switch Controlling two lights. How do I convert the 4-way to a single pole switch?

Question

Here is the situation. At the top of the stairs I have two 3 way switches. (the left one controls the upstairs hall light and the office ceiling fan/light and the right one controls the ceiling stairs light) At the bottom of the stairs is the other 3 way switch that controls the upstairs ceiling stairs light.

There is a switch next to the bedroom that controls the Hall/Office ceiling light/fan just as the switch next to the bathroom controls the Hall/Office ceiling light/fan (I will call this light switch 2) What happens in this scenario is that, not matter what the Hall light is on, ALL THE TIME (very dumb), and we will call the switch next to the bathroom light switch 3.

What I want to do, is make the light switch 2, next to the bedroom to act as a single pole switch, independent of the others.

Here are some pictures.

We will call this light switch 1 because it holds two three way switches.

Here is the wiring for light switch one with the switch to the hall pulled out.

Here is light switch 2 next to bedroom (I want this to act as a single pole switch).

Here is the wiring for light switch 2.

Here is light switch 3 next to the bathroom.

Here is the wiring for light switch 3.

Here is the situation above the stairs and "hall", which technically a hall but kind of. Stair light is present and I removed the hall light.

Answer 1

Splice the travelers through at switch 2 and slap a blank cover on that box, then cap off and cover the hall light box

Getting rid of the switch at position 2 is simple, fortunately: all you need to do is splice each traveler on one side of the switch (from switch 1) to its corresponding traveler on the other side (from switch 3). In your case, this is especially easy because the prior installer did sane things with the limited colors they had, so simply splice red to red and black to black in that box, then slap a one-gang blank cover on it.

As to ridding yourself of the hall light, that's simple too. Just cap off each wire that went to the fixture individually with a wirenut, and then put a round blank cover of the correct size on the box. Now that ex-lighting-outlet won't irritate anyone by being on all the time.
