The way I understood it, Primo's role was as a medic attached to the squad or outpost group. Medics are highly valuable to the team for obvious reasons. So they do have a value system, but I'm not sure it has much to do with anything beyond function. Remember how Paula and Chelle discuss males as little more than organic sex toys? Zero emotional attachment. I think Chelle had fondness for her father, but that was probably pre apocalypse.


The dialogue around them clearing the walkers is hazy to me now. Very possible that the only real reason for it was a dramatic device for the scene.

 

Except for the fact that they didn't know Donnie died until all the shit went down at the end.

 

That plus the fact that as soon as Paula agreed to the deal she suspected that Rick's group had already tracked them to their location (no radio static) and were planning an attack. At that point they had no choice but to make the deal or plan their own attack.

 

They may value each other in a strength in number type of deal and what each person can contribute to the group

 

They were killed off too soon to tell. But a red flag to me that they weren't quite as tough as they were trying to come across, is they revealed way too much personal information to people they just met. At this stage in the game, definitely don't let the enemy know what your vulnerabilities are. I thought the same thing of Carol when she was revealing personal info, especially by telling them Maggie was pregnant, and was thinking what others were, that it must have been a manipulative strategic ploy on her part, but then she was going to let Paula go, so there went that idea. So I'm not sure.

 

There's one thing for sure. Neither of the three women had any sympathy or use for the guy with them who was shot. They just let him lie there and if he was still alive when reinforcements came all good. But if he died before the others came, oh well.
