Scratch that previous comment just got started on this site haha.
Darcy got hired by SHIELD mainly as a mechanical engineer but also to be trained as a field agent. They saw thw potential during both Thor incidents and decided she would be a good candidate. They offered her the job and she took it needing the money and not really understanding why they wanted her. Im basing Darcy off of the same Darcy from Thor just with a few more quirks persay. Open rp. You can be whoever though Captain America or Loki would be AWESOME!
