Well, not exactly like that. Yes, Alexi does not watch the news, but he does know more than just "He's pretty" though that is a factor (Alexi's a little shallow there ya know :P) He has detailed records of everything Erik has done, and he's heard testimony from the interrogators about the rebels who have been captured and (This is my own invention) have all managed to kill themselves rather than divulging anything important with the help of humans who support the rebellion :P Alexi likes that Erik can inspire that type of devotion, or so Alexi sees it :P
