I did say no one but the MC or Holly are a good idea for long term for a reason. If Ian goes for anyone but Holly or Good Lena, he is potentially fucked. Lena runs into the exact same conundrum, although in her case its more obvious because Robert,Mike, Axel and Seymour do a very poor job at pretending to be good people while Stan is not driven. In the case of the girls Ian can end up with they have more wiggle room, the statement should still be true in that they will give you a good enough reason as to why you should not pursue them over Holly or Lena. Going for Cindy longterm is a nono because she cheated on Wade, once a cheater always a cheater. Cherry and Allison have more wiggle room at this point in the story but Allison raises some red flags with the whole possible baby trapping, while in Cherry's case it has to do with not getting over Axel of all people. What I am trying to say is that IanxAllison is harder to defend as the story goes on, heck I remember having an easy time defending Cindy but I no longer do.
