From 1:14 to 7:20, minus the exposition, and every single part with Marta in it.
This memory is what informs Emil of a lot of his anger and hate for Lloyd. It's a pretty pivotal memory for him, and is the brunt of a lot of bad things. He endures 6 months of suffering in Luin for this, and it's the thought of getting even with Lloyd that really starts driving him. Yes, he initially makes the pact to protect Marta, HOWEVER, it is getting even with Lloyd that eventually overtakes his drive to protect Marta. And this memory is part of that!
So yes, there is a lot of hate, anger, confusion, hopelessness, and guilt wrapped up into this one little memory. Hate, anger, and confusion at what happened and the senselessness of it, hopelessness and guilt because... dude just lost his parents and his mom basically told him he had to live, and that's just not enough for him with those former emotions.
However, this memory is "off." And not in a way Emil would notice, but someone else would notice something is just wrong about the memory. And that's because most of it is manufactured, so that Ratatosk can take over being Emil Castagnier. THERE ARE... A LOT OF THINGS I COULD SAY ABOUT THIS MEMORY AND ITS IMPLICATIONS but I will just leave it at the general. That Emil will... be coping kind of steady with it, but expect random bouts of depression if he's allowed to dwell on it.
THERE, LLOYD IRVING o9!!!
