Step 7: Get A Partner In Crime If You Have To

Caroline tilted her head, as if considering the question for the first time. “Want?” she echoed, feigning innocence. “Can’t a sister simply drop by for a friendly visit?”

Katherine’s laugh was humorless. “You’re about as friendly as a snake.”

Caroline grinned, clearly enjoying the tension she was stirring. “Oh, Kathy, you always did have such a flair for dramatics,” she said, standing up and smoothing down her perfectly tailored outfit. “Fine. You want the truth? I came to... offer you some advice.”

“Advice?” Katherine repeated, crossing her arms. “I can’t wait to hear this.”

Caroline stepped closer, her smile taking on a razor-sharp edge. “Let it go. Whatever little plans you’re cooking up against Castiel and me? Drop them. You’re only going to embarrass yourself.”

Katherine’s breath caught, but she recovered quickly, her anger hardening into resolve. “I don’t know what you’re talking about,” she said evenly, though her voice quivered at the edges.
