Poor Rarity, she was sprayed by a skunk weeks ago and ever since she’s been waiting out for the smell to fade, since tomato juice could permanently damage her coat and mane and a shower would left the skunk smell spread even worse.
At least Tom doesn’t care that she reeks. A loyal friend to the last. Hopefully for Rarity her unfortunate odor will wear off quickly or else she’s going to become very lonely, since she’s taking her friends into consideration because none of them would ever want to smell that bad.
