Trip had every intention of going down and exploring no matter what. Mostly the reason he didn't really want to go back and get a flashlight was because it would give Padmé the opportunity to change her mind about coming along.

"Maybe it won't be that bad," he said brightly. Because saying it might make it happen. His communications device was going to need more work on it so it was more than just a phone. But it would at least give off some light.

At the entrance he held his arm out and shined the phone's light around the drain, while trying to think back to how much rain there had been recently and therefore how wet it might be inside.
