Kara's soulmate tattoo had appeared when she was twelve. This usually implied that her soulmate would be significantly older since Kara hadn't hit puberty yet. Her parents had seemed concerned if not overly worried. It had taken the form of a single band around her wrist, much like a bracelet. If she chose to or ever needed to, Kara would be able to keep it covered easily with a bracelet.
She was oddly proud of being the first in her grade to acquire her soulmate tattoo, though it wasn't necessarily uncommon. All of the other girls Kara's age, and a few of the boys were very interested in it and loved to look at it. However, Kara's parents had raised her quite well and she didn't brag about it or show it off in any mean way. In face, she tended to just study it as a means of better understanding her soulmate.
At sixteen she started the journal. Her soulmate remained on a pretty even keel most of the time. Whoever it was was pretty levelheaded, and Kara thought that that would be good for her own hard-headed and rather excitable personality. She wondered if her own soulmate put as much thought into the marking as she did.

Cat's marking appeared when she was seventeen. She went to every high-end dermatologist that her mother could dig up, but not one of them could identify it. It wasn't at all raised above the skin and it displayed no signs of inflammation other than being warm to the touch. It didn't hurt Cat at all and she eventually came to like it. The marking set her apart, it made her special, and the way that it changed colors was kind of pretty.
Katherine pestered her for years to wear bangles or something that could cover it. She told Cat that she thought that it was gaudy, and even gross if it actually was some kind of disease. Cat thought of the mark sentimentally after three years of wearing it with pride, though. It connected her to something special, she knew. Something that was far away and beyond any Earthly understanding.
Cat wouldn't be able to understand the marking until years later after an accident. After a source turned on her, Cat found herself falling from the CatCo balcony. While working under Perry White. As he always did, Superman arrived right in the nick of time. Cat found herself in his arms, completely weightless and screaming bloody murder. She didn't think to mention her fear of heights to him as he flew to the roof of the building she had just fallen from. He set her down with unexpected gentleness; that was when she noticed it.
"Superman... off the record, what is that mark on your finger?" Cat asked, the desperation in her voice grabbing his attention.
"It's one of the few surviving remnants of my planet; a soulmate mark to help me find the person that I am meant to spend my life with. The colors change to reflect her various moods, much like the rings you humans wore back in the day." Superman's voice was eerily familiar, and Cat tried to place it while simultaneously processing everything that he had said. He holds up his hand to display what he had been speaking about. His own mark had formed around the index finger of his right hand.
Cat nodded her understanding as she rolled up her blazer sleeve in response. She held up her arm for him to see. The mark flashed from lavender to a dull gray.
"Those are dream colors. Whomever your soulmate is, they're asleep right now; deeply enough to dream." Superman explained. "Are you... Kryptonian?" he asked hesitantly.
"No, does that mean that my soulmate is?" Cat replied, wondering how that could be when Superman was the last of his kind.
"There's... there's another survivor? I don't... I don't understand how that could... I was told that I was last." his voice breaks and his eyes fill. Cat wonders who knew enough to tell him that. She wonders if she's the first person to see Superman cry.
