Starfire makes a move and Raven notices.

You keep spending time with Raven before and after the Protection Spell is applied.

You also spend plenty of time with Starfire, her being the only other Tamaranian on Earth.
Nobody is quite sure where Blackfire is at the moment.

One day, you spend some time enjoying the Titans Tower's Pool after a training session.

As you relax, the door opens and Starfire enters in a very exciting outfit.

It was a bathing suit based on her uniform, just showing plenty more skin.

She asks to join you and you agree.

You talk more, but your eyes wander a bit.
She does the same with you, to be fair.

Nearby, Raven watches without you knowing.

She gets a bit jealous.

The next day, you get the spell put on you again and tell her that you're going to train.

She knows where you'll be going after that.

Raven works up the nerve to make her move.
