Eligabolas and Severus Alexander

Severus Alexander was brought up with Eligabolas to be a priest of Sol Eligabolo. When he came to Rome, he and his mother were in the palace. Yulia Mimir and Alexander are gradually separated themselves from Eligabola's family. Eulia Mysa seems to have also transferred her affections to Alexander. Did Severus Alexander have any involvement? It's so difficult to know. He was 40 mothers though.
