Science should stay for two reasons, and two reasons only:

-He is entertaining in that he annoys the other housemates so much and as they're largely a bunch of hateful morons this year, they deserve it. Orlaith provides little entertainment.

- The look on Craigs face when Science stays. The rest of the housemates won't be happy about it, but Craigs face will be priceless!

If he was up against a housmate I like (Derek, Makosi or even Anthony) then I'd be voting to get science out, but since he's up against non-entity Orlaith he might as well stay this week.
