Lisbon knows he's a disaster waiting to happen and there's every chance she will be right there along with him. when the tornado hits, the earthquake shakes or the volcano erupts. She booked her place the moment she accepted him on her team.
That's not exactly true she could have kept him at arms length, kept it professional. Accepted his brilliant insights, and gone home at night. shutting her door to his manipulation, his chaos, his pain.
Announced by the sound of gun shot. The eruption of bullets tearing through cloth, skin, and organs. Lava of blood, tears, and destruction!
