The description can build tension because it makes the deathclaw seem more of a threat. Intelligent eyes imply that it can plan and anticipate the moves of the characters. For example, it might be stalking them in a more calculated way rather than a random attack. This makes the characters (and the readers) feel more vulnerable and increases the tension.
The significance could be that it shows the deathclaw is not just a mindless monster. Maybe it has a deeper level of understanding or consciousness, which could lead to a more complex plot where the deathclaw might not be a simple antagonist but a character with its own motives.
The significance might be related to communication. Its intelligent eyes could be a way of transmitting complex ideas or emotions. It could be a form of non - verbal communication that is unique to this dinosaur. Maybe it can hypnotize other animals or even humans with its stare to convey a message.
One possible plot could be that the dinosaur is actually a highly evolved being from an ancient civilization. It uses its intelligent eyes to communicate with the main character, perhaps leading them on a journey to discover lost knowledge. For example, it might show the character hidden caves filled with ancient writings and artifacts.
Tension can be built by introducing unexpected twists and turns. Maybe a trusted ally betrays the protagonist or a seemingly easy solution turns out to be a trap. Additionally, ratcheting up the stakes for the characters makes the story more tense.
By using the fear of being discovered. Every time they are in a group setting at work, the author can create tense moments where it seems like someone is about to find out about their relationship. For example, when another character asks a probing question or when they accidentally almost get caught in a compromising situation.
You can start by creating a sense of uncertainty. Make readers wonder what's going to happen next. Also, build up to important events slowly to increase anticipation.
You can build tension by creating time pressure for the characters or introducing unexpected obstacles.
One way is to use slow pacing and build up suspense gradually. Let the reader or viewer wonder what's coming next.
You can build romantic tension by having characters have intense emotional moments but then pull back or hesitate. Also, introducing a potential rival for one of the characters' affections can add to the tension. Subtle hints and looks exchanged between the characters can build anticipation too.
They often use the element of surprise. By having the accidental situation occur suddenly, it creates immediate tension. For example, a character might accidentally walk in on another changing, and that unexpected moment builds tension. Another way is through the characters' internal conflict. They might be shocked or hesitant about the accidental sexual situation, and this inner turmoil adds to the tension.
