There is a surreal moment there where Irahl isn't expecting to have a vivid flashback, suddenly recalling one of the last times that someone had lashed out at someone else because of him. However, this time he isn't actually as trapped in a small space as he feels. No doors are being ripped off their hinges. He's only being talked around for as long as necessary before being brought back into the discussion--probably because his thoughts are actually being taken into account, instead of him being treated like a possession to fight over. It's a refreshing take on an old theme.

Also, he has never seen Robin react like that toward anyone, and that's pretty good too.

It all adds up to an odd moment where he doesn't answer as quickly as he would have liked. He isn't expecting to need a moment to think, so there's a pause too noticeable for him to play off.

He hasn't had time to decide what he thinks about Robin--and that includes the interim months that he has spent apart from him. It's a point that he finds himself going back and forth on, and that doesn't get any clearer in the seconds that it's taking him to respond.

On one hand, he's discovering the odd thought ("odd" because him having any revelation about himself is a strange occurrence,) that having Robin leave would lower his anxiety. On the other hand, they probably still need his input, and Irahl doesn't have it in him to tell Robin to leave for a little while on his own behalf. So, that's the thought that ultimately wins the tug-of-war.

"...It's fine."
