Nah, no problem. Any kind of speculation is welcome. You actually made a very good point, even. I've also considered the idea that maybe Travis isn't vaguely referring to Mikko and Arvo and that it may have been something he did in past way before the events of Dawn Chorus; could have just been a coincidence the events sounded very similar to what happened to Arvo. It just adds more questions as to who would have taken Arvo's room key.
