I just noticed how similar to each other are these scenes. They're basicaly the same.
The first one is from Turnabout Goodbyes. He didn't talk with Phoenix for 15 years and probably expected him to treat this like a karmic justice after their trials.
But the second one happens in t&t. At this point they know each other well and Edgeworth doesn't really have a reason to think that Phoenix will react this way.
Which leads me to believe that Edgeworth's reactions here are a part of subconscious defense mechanism.
Both of this conversations take place in a difficult time for him. His dl-6 related arrest and earthquake.
He considers this events getting to him as a weakness and tries really hard to not show how it's affecting him.
His first reaction is to just avoid conversation but when that doesn't work he lashes out and puts on a facade of pride and acts like he's above any of this.
I think why he reacts this way may have something to do with MvK being his mentor. He probably shamed Edgeworth for being emotional and being an awful person he maybe even laughed at Edgeworth for this. And thats why Edgeworth subconsciously braces himself for similar reaction from others.
Sorry long post. This just made me emotional when I noticed it.
