For TWO! Yes Elijah should stop by, i'm sure Hatter would love to talk to him and just pal out while they sip tea and are awesome together. Willow should definitely come and see him! If you want he could have known Elijah or Willow from before he came here? It's possible he could have learned about the herbs witches use from Willow, to know what to pick from stores he's raided, and Elijah it might be funny if they ran into one another at a couple random points and just drank tea in random places. LOL
