The reason as to why I can see as to how Nicole’s baby is EJ’s, is because Sloan was the one who told Eric that resulted with Eric’s spiel, the main reason as to why EJ was combative & was angered, was because he was the last to be informed of it & he didn’t have a Sloan to tell him the way Sloan had told Eric, now did he? Then this, with how Colin believes that his sister had turned on him, & with how Sloan is smack dab in the middle of this, I can see as to how he would take it out on Nicole, her unborn baby & Eric, all because Eric’s new lover is Colin’s sister who is against him. Remember, some time ago, Xander had abducted a pregnant Nicole, he held her hostage & left Eric in a birdcage, can you imagine what Colin would do to Nicole, her fetus, & Eric all because his sister who he believes turned against him is smack dab in the middle of this?
