In the shadow garden from arc 6 we saw both Regulus Corneas and Betelgeuse in the shadow garden speaking to Subaru, does this mean they're both actually alive inside his shadow garden, or was Subaru just imagining it because he has both the witch factors of sloth and greed and he's seeing his impression of what the two archbishops were through his experiences of them or do they really exist inside his shadow garden like Satella? https://www.homescapesonline.com/garden/garden-ornaments.html
