Being lied to was one of the most common but greatest forms of betrayal.
A lie is always a double-edged sword.
It allowed one to attain any goal but once uncovered, leave behind a scar that will never disappear.
Once the victim realizes that they were lied to, the image of the person will forever be tainted with the grasp of lies. Such victims find it hard to find trust ever again, time is the only remedy that could ease the unrest and eventually make the victim brave enough to try and trust again.
Right after the supposed incident—compelling that bravery will be very hard.
However, it wasn't impossible.
Lucivar knew such a way and he was using it right now.
He positioned himself as someone true to himself, regardless of the situation.
A character that he already planned to showcase to Elira.
