What did E/D say during the shooting?

Besides what we heard on the 9/11 call, what do you think they were saying to each other as they were in the cafeteria, walking through the halls after they left the library? It's an interesting thought. Thoughts?

What I want to know the most is if Eric said cheers at 11:45:25

I feel all the other stuff they said was probably just communicating what they're doing and if they can see anybody/police.

I feel like Eric would be pointing things out occasionally. Monitoring everything that was happening and surveying what he could do. Dylan I think would be remarking about what he could mess up and and how the place was going to be torched. While making comments about how much fun this all was. Probably just a lot of banter back and forth of " did you see that thing f***** explode?". Pretty sure they didn't say anything like, " I'm gonna kill this guy," when shooting someone, as they just killed who they pleased whenever and obviously taunted their victims. When going down to the commons I'm sure Eric said something along the lines of, " I'll shoot one of the bombs, that'll have to set it off." And by the end of the ordeal they were just happy to turn the guns on themselves. I don't think anything to significant was said, other than comments of how they were going to die and how much damage they were going to do. Eh...

The only thing I truly want to know is if they said anything to each other before they killed themselves.  I want to know if they actually spoke to one another, or if they just merely looked at each other and nodded in a "It was nice to know you, see ya around" type of way.

This is slightly off the topic. but still relevant.
