Telumë looks like someone who is trying very hard to go on, and not quite managing it. 

:Your core memories?:

:I keep only a few dozen of my most salient memories when starting in a new incarnation, and need to re-memorize the rest from written records. I can do this fairly efficiently, but the centre of my motivations, the reason I try to do anything at all, is something I need to re-form immediately. I could show you some of it later, over Mindspeech: 

Telumë finally manages to speak. "We - were going to save all of the worlds together. He helped me to put myself back together, after Angband. When I died and came back, much of what I remember was of Arda and not Velgarth, and - about a third of everything I remembered was of him. So that is - what I had to work with. When I was trying to shape core memories." He shudders a little. "I - could show you - if you wanted..." 

Oh. 

It suddenly makes perfect sense why Telumë is terrified. 

...Leareth wants to do something to comfort him, and it feels like he really ought to be equipped to do this for himself, but he has no idea what would work. Most of the problem is that in almost any scenario, a Leareth is very difficult to comfort at all. 

"I am sorry," he says. "That sounds - very difficult. I am not upset with you about it - I will help you fix it, to the extent we decide it needs fixing..." 

:Belrun, help, does he looks like he wants a hug? I have discovered that hugging you is very nice, but I think mes are usually not hug people, but he looks so sad...: 

:You could again try asking? Like how I asked Vanyel if he wanted a hug:

:Could you ask? I think he is scared of me: It's falling into place now, sort of. :I think - he is afraid I will decide he is not meaningfully Leareth anymore, and that I will– I am not sure what he thinks I would do but possibly 'kill him' is on the list: 

:If you are going to kill him I have some objections to giving him a hug first, that being generally a signal of non-lethality:

:I am not going to kill him! I - can see why he is afraid of it, is all. I might...tell him he ought not do things, if I decide his judgement is very compromised and his actions will mostly cause harm, a me who is slightly off might be very dangerous. But - I am going to help him be all right: 

:Okay:

"Do you want a hug?"

"...Are you angry with me? I - do not want you to feel you have to give me a hug if you do not actually want to..."

Leareth cringes internally. :Belrun, the other me is so traumatized. I mean, it makes sense, but - this is quite upsetting: 

:Yeah, I don't like it either: "I'm not angry."

Telumë seems dubious of this, but he finally nods. Carefully composes his face. "Then - yes, I would like a hug." 

Belrun hugs him.

Telumë slooooooowly relaxes a little into the hug. 

"All right," Leareth says quietly, a few minutes later. "What do we do next?" 

Telumë doesn't have any ideas, so he says nothing. 

"Is the core memory discrepancy something that, say, Melody could grab out of you and put in him?"

Telumë sits up a little straighter. "Maybe. I am not sure if she could transfer it directly but she could at least compare it more clearly. She did not know me before Angband, which made some things harder." 

"So if you're comfortable with that - or want to get a Nayoki, since that's also an option - maybe that can be put back how it was, assuming that is how you'd like it."

–He should want it, right, it's a solution to the biggest problem he's been dealing with this whole time, he should be relieved and grateful, it should feel like hope and not - whatever Telumë is feeling right now, the emotion isn't helpfully naming or unpacking itself and can't make up its mind if it wants him to run away or curl up small where they might not notice him. And, in summary: internal screaming. 

"Telumë, are you all right? We do not have to do that - you do not have to decide now, even, we could simply do the comparison and - see how bad the damage is..." 

....hug? "Or not, if you don't want, I'm not going to advocate, uh. Nonconsensual mindhealing."
