Episode Summary from en.wikipedia.org:
S.H.I.E.L.D. searches for one of its assets, Dr. Franklin Hall (Ian Hart), who was kidnapped by his former research partner Ian Quinn (David Conrad). He wants to use Hall to take control over the planet's gravity by building a giant "gravitonium" generator. Heading to Malta with the team, Skye volunteers to infiltrate Quinn's mansion so that Coulson and Ward can rescue Hall. Skye tricks Quinn into believing she is betraying S.H.I.E.L.D. for Rising Tide to get his guard down. However, Coulson soon discovers that Hall perpetuated his own escape and wants to destroy the massive device. Hall believes he is in the right, but Coulson warns him doing so would end up killing millions. Their violent disagreement leads to Coulson being forced to not save Hall as he falls into the middle of the generator, seemingly vaporizing him. Coulson orders that the gravitonium be placed under high security and off the books. S.H.I.E.L.D. does not notice that Hall may still be alive.
