Sweet it loaded.
Looking good so far. A few things that I noticed right away. Screen left character is completely dead for the first two seconds, id like to see you shift that animation of him eating right away to the beginning and have a swallow or a spitting out of the food that could cue his take on its time we called the authorities. He starts his reaction before he has even heard him say authorities and I think its a little fast. He is eating something, and we dont see him do any action to swallow it or spit out before he starts talking, he couldnt swallow that fast nor could he talk like he does with food in his mouth. You will have the time to sell the eating better this way, if you utilize those two seconds of stillness. It would also be a great anticipation into his dialogue. You have some really nice thinking going on with the other character that sets up his sentence really nicely here.
Second thing that jumped out at me is that screen left character never blinks once. You may wanna throw those in there

Your screen right characters blinks are all happening really quickly and the timing is pretty much the same for all of them, it would be nice if you kept the eyes closed for a few extra frames once or twice just to give us some variety. His eyes are also really really jumpy and it is a little distracting, be nice to hit a pose with them and sell it, especially early on with the thinking.
Thirdly, wolle already mentioned the slamming/karate chop. One thing id like to see is to throw that elbow up higher, and cause its happenning so fast dont be afraid to break the joints a little even, lead that elbow up and start bringing it down even as the hand is going up to really anticipate that hit.
Its coming really nicely, looking forward to seeing some updates. Also your dialogue seems to be a couple frames off, just try opening the trax editor and slide it around a little till its synched up better.
