Eastenders - can anyone explain to me why Phil is involved with the Max thing?

[lottieandmia]

Is it because of Shirley (who I know is going to return soon)? Where has Phil even been lately?

Well Phil was in the car with carl and carl undid his seatbelt before crashing to try and kill phil and frame max for murder. So understandably phil would also be pissed off at carl.
