Ok...lemme try
a slush fund originally is a reserve fund (some money put aside for whatever) but it is often heatd in regard to corruption, when used for bribery
a hedge fund is a private investment fund (rich bastards giving money to an investment manager who promises high profits). HF usually consist of a wide portfolio incluing shares, equities etc.
They are known for their aggressive strategies and profit orientation, like in the drama: buy outs of companies which are in financial difficulties/bankrupt and reselling them in parts and liquidating the unprofitable branches (Funnily...hedge means minimizing risks...but if you wanna go into detail, let's do it in the chat)
About ruining the bank. If you ruin a bank's reputation, the price for its shares will rapidly decline, they'll lose credibility and assets (investors will draw their money out) and thus you'll be able to buy it. Otherwise they wouldn't think about selling AND it would be too expensive.
They didn't want the bank cause they needed a bank or wanted to get into that kind of business, instead, they were after the shares of other companies that are in the bank's posession.
Because this particular bank is a major shareholder of some companies (can't remember which atm), gaining control over the bank means gaining control over these companies according to the percentage of shares held by the bank.
Ok dear, it is 3:30 here and i'm not exactly sober...big chance this doesn't make any sence whatsoever...will try again tomorrow
Btw, I'm also at ep 10...so far I guess he really thinks he can teach his sister a lesson and forcing her (by making her plans fail) to think about what she's getting for what price in her life, by just focussing on economic success...I mean he doesn't have much time left...he must have reflected about life and its purpose etc...Sure he does want the girl, but he also is aware that he can't give her anything but painful memories . . .
