T3-M4 joins your party on Peragus II when you and Atton recover him in the fuel line upon entering the Fuel Depot from the Harbinger engine deck, and he must be a member of your party until you reach the Hangar. Once aboard the Ebon Hawk, T3-M4 does a circuit of the ship, which can make it hard to find him unless he's told to stop moving around:
1. Could you please stop moving around the ship? It's hard to find you.
1. You can resume your circuit of the ship, if you want.
You can maximize Influence with T3-M4 once aboard the Ebon Hawk after leaving Telos if you have Intelligence > 14 and Computer Use rank > 10, and minimize it if you have Intelligence > 14 and Computer Use rank > 14:
After completing all this, with 10 > Influence > 90 you can try working on him one last time for you to gain Wisdom: +1, have maximum Force points increased by 10, learn Moving Meditation and receive 1750XP.
Light Side Points Gained: +1 1. [Computer] Let me check your core. I'll be careful, I promise.
Dark Side Points Gained: -1 2. [Computer] That does it. I'm going to rip out your module and get some answers.
Influence Gained: T3-M4
2. I want to try and operate on your behavior core one more time.
T3-M4: Beee-deet, bee-reeeet! Deeet, deet!
Light Side Points Gained: +1 1. I want to make sure you're all right. Just let me check, all right?
Dark Side Points Gained: -1 2. I don't care what damage it could cause - I want to know what you're hiding.
Influence Gained: T3-M4
Influence Lost: T3-M4
2. I'm going to operate on your behavior core again.
Computer Use < 15
T3-M4: [Failure] Deeeeeeeeee-reeeeet!
1. Damn, that's wedged in there tight.
2. Looks like I'll need some more skill to crack that open.
T3-M4: Bee... deet. D-d-deet.
Once you have minimum Computer Use rank 15, you can unlock a message which is followed by more chances to gain or lose influence and move closer to the light and dark sides of the Force:
Computer Use > 14
T3-M4: [Success] Dee... reet.
1. I'm finished. Are you all right?
2. I'm done. You're lucky I've left you intact.
T3-M4: Bee... deet.
3. Then play the message.
2. Let's hear it, then.
3. Why was this so important?
If Revan was male, then the message is from Bastila:
Bastila: T3, you have been with us since Taris. Without you, we would never have escaped that place... and for that, I thank you. I'm leaving this message inside you because I have seen glimpses of the future... and the bond that he and I share does not allow him to hide everything from me. More of his memories have returned - and they trouble him. He has remembered something, something on the edge of the galaxy, and he believes that he must go there to end it. But I'm afraid for him... afraid that he may not return. I need you to be the beacon, T3. If he is lost out there, on the edge of the galaxy, if he finds whatever terrible thing he has seen, then he may not survive. If he doesn't make it back, then I need you to return to the Republic, find help. If you cannot find me, then seek out other Jedi, the Republic... I can't lose him, even if he believes he is protecting me.
Bastila: T3, I have one last order for you. Our master does not know about this, and I order you to keep it a secret. Every day as we build upon Korriban, more of his memories return - and the bond he and I share cannot hide it from me. He believes a threat lurks on the edge of the galaxy. Something that could threaten his power. I... fear he will go there... and I fear he will not return. If he leaves, he will take you with him - but not I. He knows the bond we share may prove a weakness... but he will take you. If something happens, T3, then I need you to return to the Republic and find me. And if you cannot, then I need you to seek whatever help you can elsewhere, whether Jedi or the Sith... or someone in-between. This is my last order to you, T3. Obey it - and do not let me lose my Master... even if he believes he is protecting me.
If Revan was female, then the message is from Carth:
Carth: T3, there's not much time - Now I've seen her start to turn as we near the end... but there's still a chance to save her. No, if I fail, I need you to do whatever you can to protect her. Now, I'm convinced that whatever the Jedi Council did, there's still some humanity left in her. There has to be. Do what you can, T3 - and if I don't make it back, then I need you to go find help. Other Jedi, the Republic, anyone you think can help... If you don't, we may lose her. And the galaxy.
Carth: T3, there's not much time - I've seen that expression on her face before. Now I don't know where she's planning on going, but it's dangerous. She's going to leave without telling me - I don't know why, but there's a chance that she'll take you. If she does, I need you to watch out for her. She's strong, but she can't face everything alone. Do what you can, T3 - if she doesn't make it back, then I need you to come back, find help. If not me, then other Jedi, the Republic... I can't lose her, even if she wants to be lost.
2. I'll try again when I've trained in my skills a little more.
Computer Use > 8
T3-M4: [Success?] Dreet?
1. All done. How do you feel?
2. That should up your processor speed.
3. Finally, maybe you'll be a little more useful around here.
T3-M4: Dee, ree, vee... Dee-deet!
1. [Due to your computer skills, T3 has gained +1 Intelligence.]
T3-M4: Dreet...? Dee-deet?
1. What do you mean, I faded out there for a second? You were shut down.
2. Glazed look? What are you talking about?
3. I was working on you the whole time. There's nothing wrong.
Experience Points (XP) Received:
250 T3 has gained +1 Intelligence
Sufficient influence can be gained or lost after escaping Peragus II before traveling to Telos: Citadel Station for T3-M4 to allow you to upgrade his memory core again with minimum Computer Use rank 15:
1. [Computer] Mind if I try to upgrade your memory core again?
