I mean, the quest he's talking about is literally the side-quest TO a side-quest... I wouldn't expect that to be too fleshed out.
Yep that's what I mean, obviously a side quest to a side quest won't have as much attention to detail compared to a high level side quest like character or planetary quests but given that they were still able to put some detail into it during and after the quest I'd say that's good.
I'm alternating between Jaal and Vetra/Liam. They are probably my favorites of the playable squad but I do enjoy them all. These three just tend to have fun little dialogue and reactions to each other. Jaal is probably my favorite of them all.
Jaal and Drack are the best for Banter. Drack also has some good lines with other NPCs during cutscenes. I generally make sure that atleast one of my squadmate is someone how has a connection to the planet, missions or the people in the mission.
