Double Grenade Glitch?

I got into a shootout with a Spartan in The Pit, and something odd happened. He chucked a grenade at me, which I fortunately shot just as it left his hand causing it to blow up in his face. Then another grenade landed at my feet, which I assumed came from another direction.
Anyway, I was watching in theater for some screenshots and thought the grenade exploding in the poor fella’s face would be neat, when I caught this: 2 Grenades, one just leaving his hand and the other still in his palm. I watched in slow motion and, both grenades leave his hand during one toss; one is shot out of the air, the other is following roughly two feet behind it and rolls to my feet.
How do you toss two grenades at once? Is this a glitch? Has anyone else encountered such a thing?

Edit: the 2nd grenade never explodes … it sits for a second or two then vanishes, but it shows a grenade warning on screen

yeah I’ve seen this more times than I can count. It makes the sound, shows up on your indicator, but doesn’t explode.

Sounds like lag if the grenade wasn’t actually physical.

That’s really weird, I’ve never heard of anything like this before, however I have seen a few dead grenades like you stated, the ones that make a grenade indicator show up but don’t explode. I’m pretty sure it was just a glitch seeing as the other grenade didn’t explode.

this also happens to me quite often, but in addition to that i never actually see the player at the act of throwing grenades. they simply chuck out of his body and I’m like wtf… though it’s obvious that lag causes this

Well that’s weird I never seen that before. Probably lag or a glitch.
