:She has infact spoken 5 times. She spoke three times in Chapter 135. The first time wasn't in a word bubble. She says "...Friends" when Natsumi asks her a question. Then as you mentioned above she spoke twice in the same panel first saying. "...For you." Then, "... a friend." Since her previous two lines were also in a similar case (She said "Negi-Sensi..." in one word bubble and "We'd love to have you at our circus, if you've the time" in another in the same pannel) I believe she's said 5 lines. I have changed her section to say that if someone disagrees that the line "...Friends" counts as a full line as it was not in a bubble feel free to change it.
