'... he was driven always to make what carnal use of them [women] he could in the fleeting moment or two he felt he had before Someone caught wise and whisked them away.' (Catch-22, 6)
Catch wise = come to senses, wakes up, regains control
Thanx a million.
someone caught wise = someone discovered what he was doing, realized what he was doing
One meaning for "catch up on something" is to become aware.
To "wise up about something" is to become aware.
Without all the prepositions: "caught wise" also means to become aware. It is slang.
