Attention shifting from Dorian to the new speaker, Shinji studied them for a moment, briefly wondering who he was. Up until Balam, Shinji had never seen anyone with red hair before (at least, natural red hair, anyway. In fact, he, personally, hadn't ever really come across anyone not of East Asian origin before arriving here).
Expression switching to one of realisation, as the other mentioned his name, Shinji nodded back at him, shaking the other's hand. "Shinji", he responded amicably. He presumed the other already knew that - or at least had an idea - but it didn't hurt to introduce himself semi-properly. "It's nice to meet you", he added, out of a mixture of habit and politeness. He'd never been all that comfortable with introductions in English - after all, how did you know it was nice to meet someone until after you'd actually met them?
