Remember my last?

Let me start দ্বারা saying I don't KNOW.

I personally believe it'd be something along the lines of 'remember the last things I ব্যক্ত to you' which presumably would be something to do with how important Harry is.

At a guess.

I think he explained her that to have her sisters sacrifice a meaning, Harry would have to stay with her moms family (meaning her) so he can be protected দ্বারা Voldemort. The things he ব্যক্ত to Harry at the end.

The 'last' was the letter he left for her with Harry, saying if she accepted him, and took him in, she would be offering him protection from Volde. He asked her ot care for Harry, and treat him as her own, and always allow his প্রথমপাতা to be with her.

That's why he ব্যক্ত what he did OotP and HBP.
