Tsunami's POV:

"Riptide," I said, spotting the SeaWing, "can you help me with my aquatic?"

"Sure," he replied, diving into the water. 

I followed him and said, in aquatic, "what are you going to teach me today?"  He flashed three scales, one after another: one on his nose, one on his tail, and one on his neck.  "What does that mean?" I asked.  He didn't answer, only continued the lesson.  I learned many words that day, though some I doubted I would ever use.

(A few weeks later)

I had been practicing my aquatic with Riptide practically every day, so I spoke it almost perfectly.  "What does this mean:" I asked him, flashing my scales: one on my nose, then one on my tail, then one on my neck.  His snout turned a darker shade of blue than the rest of his scales and he flicked his tail, a signal that told me to go up.  When my head broke the surface, I asked him, "what does it mean?"

He looked down at his talons and mumbled something quietly, to quietly to hear.  "What?"  I asked again, growing impatient.

"This," he said, flashing his scales, "means I love you."

He looked away and I flashed all of my scales as bright as I could to get his attention.  He looked at me and I flashed my scales to match what he taught me: "I love you, squidbrain"
