There's always this potential for secrets to collide and kill people as it did this week, so whose secret is the most deadly?

• Dr. Lightman - keeping secrets about his mother's suicide and Foster's husband

• Foster - keeping secrets about her husband and maybe more, we just don't know yet

• TMI Boy - lying to Foster and figuratively stabbing her in the back, maybe more? He's hiding a lot with his "radical honesty"

• The New Girl - She's still keeping her secrets, does that mean they're even worse?
