Mrs. Welch

Mrs. Welch is one of the English teachers at Rosewood High School. She is friends with Ella Montgomery and Ezra Fitz and seems to have something of a crush on the latter.

Season 1
She is first seen in "To Kill a Mocking Girl" after Aria goes to Ezra's classroom to try to persuade him to go for a date. Ezra reluctantly accepts, and Aria brushes her fingers with his on his desk. At that moment, Mrs. Welch comes in, eyeing the two of them as they jump away from each other. Aria pretends to be asking him about an assignment and leaves for the two of them to chat.

Mrs. Welch chaperones the school homecoming dance with the other English teachers, including Ella and Mr. Fitz. She is eager to relieve Aria from her duty manning one of the game booths, so that she can operate the bean bag toss alone with Mr. Fitz, who is sporting a new haircut. Little does she know that she is interrupting an important conversation between Ezra and Aria by doing so. Later, Ezra makes a comment to Aria about his fresh haircut, sarcastically pointing out that he hadn't gotten it for Mrs. Welch to admire.

In "The New Normal," Ella, Ezra, and Mrs. Welch are seen lunching together in the cafeteria. (Some other unnamed teachers are sitting with them as well.) The three discuss an upcoming book event that Mr. Fitz invites his colleagues to attend with him. Mrs. Welch is very excited about Mr. Fitz' suggestion and convinces Ella to come along. Suddenly, Mrs. Welch and Ella are both witness to Paige McCullers' father denouncing Emily in the lunch room and watch admiringly as Mr. Fitz takes control of the situation

Season 2
Mrs. Welch returns in "Let the Water Hold Me Down." Ezra Fitz offers her a spare ticket to a play.

Mrs. Welch returns again in "The Naked Truth," and her character is involved in a stunt.
