I actually like the part about Arthur. I was thinking something similar.

Probably works something like this:

1. Regina reveals that she has the DO Dagger. (Not intentionally or maliciously).

2. Arthur gets the idea to steal the dagger in order to complete Excalibur.

3. Emma finds out, and somehow gets involved with Excalibur (which may be the excess baggage they find in Episode 2).
