Sana & probably a few others think that if something isn't related to sexuality, it's not a character trait. LoL
Trust & trust worthiness is very much a character quality of a person. A flipper for self interest or others interest displays these qualities; so Sid was absolutely right.
Funny thing is, she tells Sid that they will be free to do anything in a task and he shouldn't interfere; but when Sid does the same, she has problem and she needs to interfere. She wants benefits at both ends of it.
What a shamelessly selfish girl she is; which is another way that she shows her character. š
