It was hard, but she hid her tail at first. She coiled it around her torso and leg as she wasn't sure how Kelly would have reacted without proper explaining first. She herself still wasn't fully on board with this - her brain took over control as if it was there since forever. Her subconscious however was continually forgetting and finding out with every move it made.
Her friend Kelly welcomed her warmly, although Mary politely rejected her hug, saying she's not feeling her best, but looking forward to the movie still. She was standing in the kitchen preparing snacks while Kelly was putting on the movie in the living room. Before her on the counter the open box, vials staring silently at her. End of her tail was twitching slightly, nervously.
Should she talk to Kelly? She might not take it as well as her and reject her as alien. Or maybe just be weirded out but supportive? She could slip the vials into her cola. That would be so fucked up, doing it without her consent... But I guess it could be reversed with the human vial? And she would be forced to accept it that way...
Her hand reached out.
