I'm guessing that the chocolates are poisoned. The staff will be dropping like flies and this will give the opportunity for Clark and Lois to make the connection.
Also it's probably a good idea that Ina is in the new room - I feel like this is a suspenseful movie and the "da-dum" music is playing. I expect someone to sneak into Ina's old room and try to murder her - but tee-hee, she's not there!
