So, do you guys think Enigma requested the Foundation not to throw away any of his sister's personal belongings because he plans to give all of them to Marcus when the right time comes.
Personal headcanon: Enigma treats her nicely because somehow she became family since they both lost the same person (a sister and a mentor/mother figure)
Maybe he even requested to be called Adler by her but I believe Marcus is too shy for that.
