Star Wars: Knights of the Old Republic/Carth

You can speak to Carth the moment you regain control in your after arriving on ../Taris/. If you don't speak to him when he's in your party, then you may be prompted to do so:

Speaking to him can unlock the quest for his son,, once a second Star Map has been acquired. A female character can unlock further dialogs to romance him, which can be completed once a third Star Map has also been acquired. Ideally, these dialogs should be completed before acquiring a fourth Star Map and leaving that world, although they only become completely unavailable once Darth Malak has been encountered for the first time, in the hangar of the Leviathan...

s can unlock further dialogs once previous dialogs have been completed, but so can entering and exiting the on Taris, and later the ../Ebon Hawk/, and adding Carth to your party (you may also be able to speak to him in the  inside, but it's quicker to just enter and exit before speaking outside). Acquiring Star Maps is necessary before later dialogs can be unlocked, and the first will be unlocked automatically if all previous dialogs have already been unlocked and completed.

Four further dialogs can now be unlocked.

First
A female character can flirt with him:

Otherwise:


 * }

Second
Otherwise:

A female character can take it even more personally:


 * }

Third

 * }

Fourth
Otherwise:


 * }

This is as far as you can advance this quest before escaping Taris, although it isn't necessary to do so at this point.

First Star Map
A dialog can be unlocked after acquiring the first on ../Dantooine/.

Fifth

 * }

Second Star Map
Two more dialogs can be unlocked after acquiring a second Star Map with a male character, and three with a female.

Sixth

 * }

That response completes this quest prematurely. Otherwise:


 * }

Seventh

 * }

That response completes this quest, preventing a female character from romancing Carth but still allowing both male and female to unlock. Otherwise:


 * }

This also completes this quest for a male character.

Eighth
A female character can continue to romance Carth:


 * }

That response completes this quest prematurely. Otherwise:


 * }

Third Star Map
Four more dialogs can be unlocked after acquiring a third Star Map with a female character, although only the first three need to be completed to romance Carth.

Ninth

 * }

That response completes this quest prematurely. Otherwise:


 * }

Tenth

 * }

Eleventh

 * }

Either of those responses completes this quest prematurely. Otherwise:


 * }

This dialog completes the romance with Carth until a fifth Star Map has been acquired and you're ready to travel to the ../Unknown World/, and it must be completed before Darth Malak has been encountered for the first time, in the hangar of the Leviathan (so ideally, before acquiring a fourth Star Map and leaving that world).

Twelfth
This final dialog is actually optional:

Otherwise:

Otherwise:


 * }

Otherwise:


 * }

In either case, the romance with Carth has already been completed, at least until a fifth Star Map is acquired...

Finding Dustil
After acquiring a second Star Map, and unlocking and completing the unlocked dialog, if Carth is in your party then a man named Jordo may approach and speak to you in one of the following locations:


 * }

Some experience and items are received while completing this quest, and you can move (much) closer to the light side of the Force. If you speak to Carth at any time before on ../Korriban/:

However, once this quest is activated a female character cannot continue to romance Carth until it's been completed with Dustil's eyes opened to the true nature of the Sith, so if you want to romance him then you might want to avoid activating it until that romance is complete (completing this quest is not necessary to complete the romance, although if you want to do so then it must be unlocked before Darth Malak has been encountered in the hangar of the Leviathan, ideally before acquiring a fourth Star Map and leaving that world). If Dustil's eyes are closed, any romance ends:


 * }

So a dark side female who wants to romance him should either avoid this quest entirely or complete it as soon as possible after acquiring a second Star Map, to avoid wasting dark side points (since you normally move (much) closer to the light side of the Force the closer to the dark you already are), even on Dantooine itself: return later to claim the reward for destroying the, find the , and investigate the , ../Sandral-Matale Feud/ and , but before acquiring your fourth Star Map. You should also acquire your second Star Map on Tatooine, since you can do so without squandering opportunities to move closer to the dark (although these are much more common than those to move closer to the light, so don't be too concerned).

Banter
Carth may speak to other party members as well when both are in your party:
