"Echo 419 to Cortana, come in." - In the rock - slide crash site.
"Roger, Cortana. On my way. I've spotted additional lifeboats in your area. One near the cliff edge. And another near the head of the river. Hard to see from my altitude, but it looks like there are more survivors."
"Echo 419 to Cortana. Foe Hammer's on station and ready for another pick-up." - In the river - head crash site.
"Roger that. I'm on my way." - In the cliff - edge crash site, after all the Covenant forces are dead.

"Roger. Echo 419 inbound." - To Cortana.
"Negative, Cortana, I've been engaged by Covenant air patrols, and I'm havin' a tough time shakin' 'em. You'll be better off findin' your own ride. Sorry." - When Cortana requested for the reinforcements, after Captain Keyes and a few Marines were released from the Covenant prison.

"The last transmission from the Captain's dropship was from this area. That was over twelve hours ago. When you locate Captain Keyes, radio in, and I'll come pick you up." - In the beginning of the level 343 Guilty Spark.
"This is Echo 419. Chief, is that you? I lost your signal when you disappeared inside the structure. What's going on down there? I'm tracking movement all over the place!" - Near the top side, level 343 Guilty Spark.
"There's a large tower a few hundred meters from your current position. Find a way above the fog and foliage canopy and I can move in and pick you up." - To the Master Chief and a group of Marines.
"Chief, I've lost your signal! Where'd you go? Chief? Chief!" - When the Master Chief was teleported by 343 Guilty Spark.
