I made a thread on the BL1 forum about dialouge checks you can miss if you always fast travel right here
So this will be an offshott of this thread where i talk about the same thing, but in borderlands 2. I also heavily suggest we all playthrough some things like the main story quests, DLC, and side quests without using fast travels to see what we can find out.
The main reason im posting this is because i found 2 things in the captain scarlett DLC. The first thing is when you have the quest to kill sandman and you travel to oasis from wurmwater, you get some scarlett dialouge you probably, but might not know about. Its not that big of a deal.
However, after you kill sandman,and travel to wurmwarer, if you happen to die from the super badass loaders initially guarding the caravan and spawn back at the entrance to wurmwater like i did, because you entered from there of course, you might get a scripted sequence that i got. I dont want to spoil it, but OH MY GOD. If you dont know what happens there, you will be as floored as i was seeing it for the first time.
I’ll have to check that out. I heard an NPC say something the other day that I hadn’t noticed before, but probably because I just hadn’t noticed it.
I’ve found something of this kind just recently: in Liar’s Berg, while following ClapTrap, he’ll be talking about Boom and Bewm until the gate; at that point Jack will pop on the Echonet munching Preztels. If one stops before crossing the gate and waits few seconds, ClapTrap will turn around and say a line that can’t be heard otherwise.
