User blog comment:CrimsonShogun/Omega DLC (and Nyreen!)/@comment-50.8.235.70-20121113051042/@comment-5607736-20121116155534

The J Hat is correct it states that neither Aria or Nyreen will be full time squad members. It further states that Romances with each one will not be possible. It does say that Aria and shepard can become either Very close or far apart depending on your choices. I forgot what site says this, type in mass effect 3 omega into google and read one of the links on the first page, that should do it.
