Lalo will rest for a total of three hours. He'll sleep for two hours, then spend a third hour drinking some more water and just resting, waiting to see if Jet catches up with him before he's on the move again. He's going to be hesitant to eat anything though, lest that trigger another bout of sickness.

After three hours, since it'll be dark, he'll light himself another torch to see by and start moving towards the concrete structure. He'll move as fast as he can without hurting himself, considering his hindrances. If they haven't already found each other/met up yet, Lalo will text Jet to let him know he's on the move again and his trajectory, and he'll keep an eye out for Jet on the way there. Now rested, should Jet have failed to find an adequate walking stick, Lalo can serve as a bulwark to lean on while they walk back together. A staggery, limp-y bullwark, but he'll do the job.

If Jet catches up with Lalo well before the three hours' rest are up, Lalo will let Jet take the supplies and go on ahead without him. If Jet catches up to him near the end of the three hours, they'll leave together with the supplies and possibly share the load in carrying them.

He'll stop once he gets to the concrete structure with the supplies (and Jet).
