April Martimer is a scientist, and a member of the Followers of the Apocalypse. She will express her interest in examining ED-E, a prototype duraframe eyebot carrying Poseidon Energy research data, so that she can extract the data and put it to good use in the future. She resents the Brotherhood of Steel, who also has interest in the eyebot, since they will be using the data to their own benefit.
She will contact the Courier through ED-E once its audio logs are unlocked. Once ED-E is upgraded either by her or the Brotherhood, she will vanish from the fort.
ED-E My Love: Martimer will appear at the Old Mormon Fort once her recorded message has been played after a certain progression into this quest. When talked to, she'll explain that ED-E's data banks will serve a greater purpose than what the Brotherhood of Steel intends to do. If she is chosen, ED-E's data will be extracted and its weapons system will be upgraded. Once ED-E is upgraded, she will vanish from the fort.
Interestingly, although she harshly criticizes the Brotherhood of Steel for potentially using ED-E for weapons research, she doesn't hesitate to explain that she will upgrade ED-E's weapons system. The bonus ED-E gains increases his weapon's power output.
