Vetra isn't impressed with Suvi's movie night snacks. She's tracked down alternatives on Kadara.
Speak with Vetra after Ryder has returned to the Tempest after visiting Kadara Port. There is also an email from her asking to speak to Ryder, though it is not necessary to read the email.
Vetra has got her eyes on some contraband that would make excellent snacks: popcorn and graxen, evidently the turian version of popcorn.
Procure snacks from Kadara PortEdit
Buy the snacks from the Mods Merchant.
Return the snacks to Vetra on the TempestEdit
The popcorn and graxen is handed over to Vetra.
