Rowan showed a lot of interest as the Captain entered the room. Seeing the man's rank insignia and his uniform, he recognized that he was important and quickly stood and saluted, before dropping the salute and sitting back down. He listened patiently and kept his attention on the man as he introduced himself, and most politely at that. As he asked his questions and finished, the black-haired pilot considered his answers carefully before replying.
"Well, Captain Hiyan, thank you for introducing yourself to me, and doing me the courtesy of hearing me out. I appreciate that greatly, sir. Especially if you're in command of this group. As for who I am, and what I came here for, well. I'll try to explain as best I can".

Rowan explained with a concise version of the AEUG and the Titans, and the connections to Zeon and Neo-Zeon, as of the time he'd left. He gave as relevant a discussion as he could; the One-Year War, the split between the Titans and the AEUG, and the following Gryps conflict, and whatever other information he could define as being relevant, before finishing with his account of being part of Task Force Alpha, and departing to aid in the suppression of the New Desides rebellion that had lead him to coming to around the other group.

"I can't say that I'd heard of some of the other names of the groups they mentioned when I was with them. The word 'junker' came up a lot in reference to me and my suit by one guy by the name of Victor. He had an arrogant streak the size of a space colony. And there was another man, younger and very, hmm... 'self-assured' and kinda headstrong. He seemed like he was familiar with my world, but from a different time, maybe. His name was Angelo. And there were a lot of others, too". 
He went on to describe the mobile suits he'd seen, and as many names as he remembered, before shrugging apologetically. 
"I'm sorry, Captain - that's as much as I remember, or that I can tell you right now. I don't know any more than that, other than I didn't like a lot of what I saw of those people, and knowing what I do about Zeon - or Neo-Zeon, as this Angelo Guy seemed to be - then I didn't want to spend too long hanging around there. And if they were opposed to people and looking to attack them, I figured I'd want to check out who else was around, in case it was someone I might know better, or fit in with more. And while I can't say that I've heard of OMNI - begging your pardon, and no offence intended - I think they sound a lot more like the AEUG or the Federation before the Titans than anything else I've heard, Sir. My chance to escape and get out of there came because they were planning an attack to begin with, and saw me as a disposable scout. There was a woman, too, who they were going to send out ahead as well, though she seemed pretty okay with being there... although a little out of it. Stella, her name was. Anyway, they said they were planning to attack tomorrow". The long-haired pilot outlined the plans he'd heard to the captain, trying to explain as much of the detail as he could recall from the briefing held just before he'd left. 

He gave a defeated look and clasped his hands together on the table as his conversation ran out of steam, having mentioned everything he felt he could. "That's about it, Captain. I'm lost here as much as anyone else, I'd imagine, and just trying to do what I think is best and right, as well as closest to my duty as I see it. If my Zeta Plus Gundam and I can help you, then I'd be pleased to do so. And I can understand why you'd want to know as much as possible before anything else happens" He gave another shrug and a frown. "And I know 'name, rank and serial number' is normal for an interrogation - but I came to you, and didn't get captured as a hostile. So I figure there's no point in me withholding information from you at this stage. It isn't likely to help anyone involved".
