In S02E10 of Marvel's Agents of S.H.I.E.L.D.,
Coulson went into tunnel to save Skye and to satisfy his curiosity despite he knew about bomb they implanted. Knowing that, Trip jumped into the tunnel without protective suit to disarm all bombs to save Coulson and Skye.
It could turn out to be an extinction level event for Mankind. What was Tripp thinking? Was saving few lives necessary over survival of human race or Earth?
