None of the above, daddy is upset.

Robbie had been so intent with Eliza and Angela, that he didn't scene when Goliath arived.

Goliath was already seeing red when he noticed Robbie and Eliza were both naked but held back because he could sence powerful magic at work, but when Robbie had started to seduce his innocent daughter and bring in Eliza it was just too much.

With a defining roar, Goliath burst into Eliza's apartment and knocked the Key from Robbies hand.

Robbie wasn't too worried, even without the key in his possesion he was still immortal here as well as immune from any changes someone else may make with the key. Of course being immortal didn't mean that what ever Goliath was about to do to him wouldn't hurt, and he couldn't make any more changes until he got the key back.
