The second Peter saw Alec get bit in the thigh was the moment he knew he needed to get up. He tried to push himself up off the ground, but even when he was pushing it, he couldn't get up much further than he did before.

There's four of them left. Two on Alec, and the other two rounding Alec from either side.

"I'm really sorry about this," he tells the hyena lunging towards him. He sends a string of web-slinger fluid towards the maw of one of the hyenas, then using his upper-body strength, spins him right towards the other hyena.

The hyenas don't make impact, but the tight line of web-slinger fluid trips up the other hyena when he gave it a spin. While the other hyena is down for the count, that one scrambles up, and when it growls it becomes abundantly clear that it isn't. The hyena races towards him.

Peter tries to shoot out another string of spray, but only a short line comes out. He presses his finger against the webslinger again, but nothing comes out.

The cartridge was empty.

"Oh, come on!"

Why didn't he grab a new cartridge before he left?
