Eliza would feel the familiar buildup of tension in Martin's body when she stepped forward, embraced him, and then kissed him (though not in a super-open manner).  Right...Mentats.  Had the whole 'human computer' thing going on; had issues with intimacy and being touched in particular ways, and Martin was no exception - perhaps in fact too much the rule!  But, he was able to avoid showing it openly - the only reason Eliza could tell was because she was directly touching the Mentat, and bodily control of that magnitude was much more difficult.  Leaning back, he delivered his answer to her, turning his head towards her neck.  "Slowly, but surely," he quietly confessed.  "If I can remain at this long enough, our friend the Guildsman will let something go.  What that will be, and how it will be of use to us...none can say.  Not yet."
