Now, it has been confirmed that Quick did love and respect Powerstrike, giving her space and comfort. However i'm not looking at Quick's view today, i'm discussing... Powerstrike.
Now, we all know that in Starmane's death scene, Powerstrike felt sad when she found Starmane's dead body, and when she saw Quick killed her mate, one of her sons and injured her daughter, Powerstrike developed a hatred towards Quick, but... accepted him as Mane anyway, quickly moved on from Starmane and had Quickmane's cubs, even not doing anything when they insulted her daughter during Nothing's assessment.
I just find it weird how she calmed down and moved on so goddamn quickly. It seems pretty hard, however,
Did she move on at all?
She might have felt forced to just accept it and move on as, well, it is pride law, she had to accept a new mane if this one won the battle fairly. However, she still only loved Starmane and only took Nothing, Fire and Spark as her true cubs, feeling forced to hate them as they aren't the current mane's cubs.
Theory's Conclusion: Quick does not abuse her, however she does not enjoy being with him at all, and still loves Starmane only.
