Pride saw her talking to Greed who was only trying to get close to her so Kalinda would trust her more. When Pride saw this, he was freaking out. Especially because this was around the time he got his hair torn out.

Pride was acting irrational out of fear and pulled Eloise away by her arm. Greed grabbed by by the wing and soon one whole wing sewn to her overalls was accidentally torn off.

Pride then opened a portal to his realm to get her away from him.

At first, Eloise was terrified. From childhood she had heard stories about how merciless the god of lies was and how selfish he was. But after spending more time with his family and how things were for his followers, she changed her opinion on him, especially since he sewn a new wing for her. 

Greed told Kalinda about Pride taking Eloise to his realm. "It was horrible! He just grabbed her! I tried to save her but he wouldn't let go! He pushed her into a portal even when she was screaming!" Obviously, this upset her family. Kalinda opened a portal to Pride's realm and rushed to his palace, finding her daughter making sunflower crowns in the garden. 

She didn't understand why she was acting so happy in 'Such a horrible place'. She fully explained why to her mother and after a long conversation, finally convinced her to trust him. When giving him a chance, she finally realized how bad Greed was but still has an alliance with Greed since he provides her with supplies for her followers.
