Situation: a near-epic Battlemind and her Cleric friend are standing adjacent to each other, 3 squares away from a Yuan-ti Anathema with no intervening cover or interesting fiddly bits.

The anathema uses Double Attack, which:

The yuan-ti anathema makes two slam attacks, each against a different target.

and targets the battlemind and the cleric.

The battlemind then uses her II to invoke lightning Rush and hits with her augment 2.

Does the battlemind then:

1. Get targeted by double attack once or twice?
2. Get one or two attack rolls?

Would there be a difference if the Yuan-ti used bite against the cleric, or moved and used horde of snakes?
