How to Start the Close Comrades Affinity Mission
In Xenoblade Chronicles X: Definitive Edition, affinity and main story missions are unique in that you can only undertake one at a time. If you begin an affinity mission, you won’t be able to start a main story mission, and vice versa. Furthermore, you can only have one affinity or story mission active at any given time.

The Close Comrades affinity mission in Xenoblade Chronicles X: Definitive Edition becomes available after completing Chapter 4. This mission can be found in NLA’s Administrative District. The recommended and required level for this mission is 20. Doug and Lao are restricted characters. The primary destination for this mission is Noctilum.
Close Comrades Walkthrough
You took on a Pathfinder task with Doug in place of Lao. Head to Noctilum and investigate.
Collect data at Noctilum’s Decapotamon

First, you’ll need to collect the data from the unusual plant at the Nopon Braidbridge.

Interact with it then head northwest to the next spot. Again, interact with the unusual plant. From this spot, head north to find the next spot atop a hill. Interact with the unusual plant to trigger a cutscene.
Collect the fourth piece of data at Noctilum’s Qing Long Glade

Travel to the southeastern side of Qing Long Glade. As you approach the unusual plant a cutscene will trigger.

After the cutscene, you’ll engage in a fight against five Level 15 Arrow Germivore. Take them all out! A quick cutscene will trigger and you’ll be able to add Doug to your party.
Afterward, fight more of the Level 14 Arrow Germivores that spawn and the giant Level 18 Arrow Cinicula.
