Mariel Rodriguez is back inside the Pinoy Big Brother House during the 5th eviction night of Pinoy Big Brother Celebrity Edition 2 where Donnie Geisler was evicted while Jon Avila and Will Devaughn stays. Mariel already got out of the house as Celebrity houseguest and now she is back with a new task as a Big Sister. Another twist Ethel talked to big brother in the confession room too if she can go back inside the house after voluntarily exited with Macoy. She wanted to go back not for the winning prize but because she misses her new friends -the housemates and after knowing the facts outside the house about her boyfriend Janvier Daily (Janvier drop their relationship). Big brother have not decided yet on Ethel's request but for sure she'll be given a chance even not as a housemate but as another big brother's spy inside the house.
