I suggest to discuss about "reported speech". Any suggestion can be helpful. Thanks.
Verbs used in the original speech generally become more ‘past’ (i.e. they often go back a tense) but some of them stay the same:
present simple > past simple
present progressive > past progressive
past simple > past perfect (or remains as past simple)
present perfect > past perfect
past progressive > past perfect progressive (or remains as past progressive)
past perfect remains as past perfect
can/may/shall/will > could/might/should/would
would, could, should, ought to and might remain the same
must > had to (or remains as must)
Mary: "I will eat steak for dinner."
Jill: "Mary said (that) she …………… eat steak for dinner."
Mary: "I'm going to go to
Jill: "Mary said (that) she ……………. going to go to
