I, Thou, We

According to Levinas, 'Ethics' begins with the intrusion of the Face of an Other into Phenomenological Interiority.  As has been proposed here, a divergence from that scenario is that 'Ethics' begins with the response to that intrusion--either a welcoming, or a reduction to another mere phenomenon.  Now, such a welcoming is constituted by the I and the Thou combining as a We.  So, according to this variation of Levinas' scenario, the cardinal moment of Ethics is the formation of We on the occasion of one's encounter with radical Alterity.
