Alexander Robespierre's Links
Jane at first sees Alex as another person to fool, much like she does with Engou. But as she realizes that she work together with him -- that they can do murders and get away with it -- she puts a degree of trust with Alex when playing DRcade with him.
However, by the end, when she's forced to always lie...not only does she recognize that Alex can see through her words, but that in truth, she wanted to speak her mind. Post game, she wonders just what sort of person Alex was irl, and considers him her one true friend.
