Help! The last few puzzles

[Janakev]

This is actually one of my favourite puzzles.

Spoiler below!

Reconsider what you are asked to do. Philip notes that he feels as if some part of him dies when that man dies; the Tuurngait note that the needs of the many, outweigh the life of just one. If that man is linked to you then...

That's the first hint, if you're still stuck:

Spoiler below!

The Tuurngait are essentially presenting with the scenario that you are a part of something greater than yourself, something that is made of both you and that other man. Together you are many and one of you must sacrafice yourselves to continue on.

Third hint:

Spoiler below!

You must find a way to prevent that man from killing himself, you've no doubt figured that out. When you respawn look behind you. There will be a pressure plate. Investigate what happens from that.

Fourth hint:

Spoiler below!

The pressure plate behind you controls the door just in front of you. Inside you will find another pressure plate and a switch. Experiment

Fifth hint:

Spoiler below!

The pressure plate within this small 'room' controls the door out which the other man runs. The switch temporarily holds open the door into the room you are now in when you remove the block that is on the pressure plate to open it. You must move the block outside onto the pressure plate inside, thus closing the door of the other mans cell. I think you know what needs to be done.

Final hint:

Spoiler below!

You are just one but with the other man you make many. You must sacrifice your life so that the many can continue. As counter-intuitive as that sounds you have to think like the Tuurngait: hive-mind is as natural to them as individualism is to us. If one of them must die so that the rest may live it is done without a moments thought.

Good luck!
