Keep notes when you play a game. Not just so that you don't have to remember stuff, but also so you can pull your GM up with written evidence when inevitably something contradicts when previously happened on the adventure. (Unless it's in your favour, in which case quietly ignore your written notes.)
Do be aware though, that GMs tend to take notes as a matter of course when running a game, so you're a little behind the 8-ball to begin with.

Obfuscation by honesty. Tell me where Luke is; I don't know. You went with him; oh yes.
Truthful answers. But not the sort of answers that the big bad is looking for. And then more delay. The old person's memory defense.
And then yet another reminder that all he is doing is successfully delaying this Vader wannabe.
I can almost see the next line coming out of Kylo as, "tell me what I want to know or I start shooting the innocent civilians". But I think that would be giving Kylo too much credit.

Now this is the proper way to deal with a villain you don't like. Truthfully answer their questions in the most frustrating way while still being helpful enough so that they don't immediately cut you down for being annoying. Also good is the bit about not remembering where Ahch-To is, whether or not it's actually a lie. Inventing fiction can be difficult, and making it consistent even more so without notes.
Weirdly though, note taking is one of the best ways for me to try and remember things, though mostly only when physically writing. There's a lot of different ways people learn information or how to do tasks like videos, instructional manuals, lectures, reading textbooks, watching someone perform the task online or in person; it all depends on who you are. Using metacognition, or the awareness of your own thought processes, can help pick out learning methods that suit you best to quickly adapt in new life experiences. Or in some cases like Lor's, minimize potential future problems.
Kylo really should have sent their troopers off to track Poe down before continuing Lor's interrogation after the two minute headstart comment.
Kylo Ren: Tell me where Luke Amidala is.
Lor: I don’t know.
Kylo Ren: You went with him to the lost world of Ahch-To...
Lor: Oh yes.
Kylo Ren: Well, where is that?
Kylo Ren: Can’t you remember?
Lor: I wrote it down in my expedition log so that I wouldn’t have to remember.
Kylo Ren: And. Where. Is. That?
Lor: Oh, the pilot has it.
Lor: And now he has a three minute head start.
Lor: Which is more than more than he needs.
