Omni had been bored and hanging around his home when he noticed a bit of pink down the beach. Knowing of one person, so far, here that had pink hair he decided to head on down that way. If it wasn't Mizuki, he wouldn't be adverse to chatting with someone new anyways. He was half way there when the TARDIS showed up. It put an immediate scowl on his face. That TARDIS meant the presence of a timelord he didn't particularly care for. The Doctor, his father's mortal enemy and obsession.
So he slowed, but didn't stop his travels towards them. He was amused to see where the TARDIS had landed. As he finally arrived he managed a broad friendly grin for the two women there. "Mizuki, Ms. Tyler, a pleasure to see you both again." He purposively ignored the Doctor's presence for the most part. What was the Master's human girlfriend doing here with the Doctor? At least he assumed it was a regeneration of the Doctor given the TARDIS and all. Who else would have a TARDIS like that?
