Note 7.4 — SIN QUERER
Reading edition
¿Qué iba yo a cambiar...? 'What was I going to change in a saint [if I married one]?' i.e. 'What could I change?' The conditional of poder would be an obvious conventional form, but the imperfect indicative and the verb ir add strength to the question; cf. the English 'What are you going to do about it?'
