After Alena noticed someone who appeared to be Felicity Smoak hacking the NSA to no results, she contacted her via terminal message, offering her help. The two soon met in real life, Alena excited to meet her idol. She explained Felicity's inspiration to her, before handing her the USB flash drive containing Pandora, hoping to not only exonerate her friend but to inspire her to return to her hacking roots.

After Felicity used Pandora to locate dirt on General J.G. Walker, Alena urged her to use Pandora's capabilities on a larger scale.

Alena soon met with Felicity, who decided that she wished to join Helix.

Leaving Helix
After freeing Cayden James, Alena noticed that his time in ARGUS had changed him. When Alena disagreed with his plans, Cayden attacked her. Alena would escape, and believed that Cayden was still in Corto Maltese. Alena would later break into Felicity's apartment to ask her for help. They would obtain a ghost mirror drive from Amnesiac, and would later go to the old Helix building in order to discover what Cayden was doing. However, Felicity and Alena were confronted by Black Siren] and Cayden James, who was about to execute them if not for [[Team Arrow. However, Alena was shot during the conflict, and had to be brought to the hospital.

Felicity would later visit Alena in the hospital, and when asked what Alena was going to do now, Alena said she was going to take some time to get some much needed perspective. Alena then asked that after, if she could join Felicity's startup, which Felicity accepted. Alena then gave Felicity her pitch, mass producing Felicity's bio-stimulant implant.
