Does anyone else kinda think Katrina changed when she became Louise's associate/ bestie?

See I'm rewatching suits (for like the 5 time lol) and I've noticed this time round that Katrina changes a fair bit when she makes the change over to Louis. Like she used to be this very trickstery lawyer as we see in her first interactions with Mike at the firm but as she progresses with Lewis she seems to become much of a Louis yes man. And almost kinda loses her individuality until much later on in the series. Does anyone else share this view or am I just kinda seeing it weird?
