Iliad 3:383

[Bert]

αá½￾Ï„á½´ δ' αὖθ' Ἑλένην καλέους' ἴε

αá½￾Ï„á½µ seems to indicate some emphasis but I don't see a reason for it.
The subject in the line before is Apophrodites and she is the subject here as well.
Why the emphasis?

[modus.irrealis]

Could it be that she is going in person (herself) to call Helen instead of sending someone else?
