How to Turn Ashley Paragon

In a similar process to turning Kaidan renegade, Ashley can be changed to be "paragon" in the first Mass Effect game. However, she will change for the better by becoming less xenophobic and more open minding about aliens.

If you want to change Ashley, you must play as male Shepard and romance her. As usual, talk to her after every main mission and be kind to her.

Eventually, Ashley will offer to have a drink with her and tell the story about her grandfather surrendering at Shanxi. During this conversation, listen for when Ashley says, “But hey, maybe once we saved the galaxy the Alliance will get its act together. Start acting like an actual government.” Respond to this by picking the “Alliance is all right” (top right) option on the dialog wheel. On the following dialog wheel, you can pick any of the three options. After going through these two dialog wheels, charm and renegade options will open up. Pick the charm to turn Ashley paragon.

All that is left is to do is to take the romance to completion. When Ashley comes to Shepard's cabin to spend the night with him, she should make a comment, “I couldn't blame the Council for calling us reckless or aggressive”. This confirms that you have successfully changed Ashley.
