I've befriended the Birds, Mewtwo, HO-oh, But Alakazam doesn't tell me anything apart from the ranking thing and Gengar doesn't appears to help him, I have saved Medicham from the wish cave but not befriended Jirachi( Asked a wish).
Is there something I'am missing
PS: I HAVE cleared the Stormy sea

Someone is there?, What do I need to do???

Do I need to befriend Jirachi to open the Silver Trench?
What should I carry?
When will Gengar appear?

to get silver trench you not only have to get the three birds but you also have to do the latios and latias event and on the next day or something like that alakazam should be by the entrance of wishcash pond then go to the birds friend area then you will have access to silver trench.

And you need Surf for Latios's mission.

i also had the same problem. i recruited kyogre and the latioses and the legendary birds. alakazam still only said about lucario whenn i talked to him. but then when i told the spinda about the mirage pokemon ho-oh(i had already defeated ho-oh)spinda went away. and then i went to my home and next time i went to the pokemon square alakazam was standing near the persian bank. ps:i didnt completethe buried relic yet so you dont need it
