But the Irishman left his players with no uncertainties after slamming their heartless display in the first half in Leith.
The home side trudged off at the break with boos ringing round Easter Road after Stuart Armstrong opened the scoring for the Tangerines in the 29th minute.
It looked set to be a fifth defeat in as many games and yet more humiliation for Fenlon after a 9-0 aggregate defeat to Malmo in the Europa League and defeat to Hearts in last week's Edinburgh derby.
But, after both sides were reduced to 10 men following red cards for Kevin Thomson and Gavin Gunning issued for an off-the-ball fracas, Hibs rallied to level through Scott Robertson with nine minutes left.
Fenlon said: "I suppose that we scored and picked up a point, there is a bit of relief.
"But it wasn't a great performance to be honest with you, especially in the first half, when we were very, very poor.
"The sending-off seemed to galvanise us for some reason and we seemed to get going. I don't know why that happened. Afterwards we wanted to fight and scrap for the ball. But we didn't want to do that before.
"That was the disappointing thing. I said to the boys at half-time that they hadn't shown any passion or desire to win the game. We were beaten by our big rivals last week and we should have come into this one bouncing and with a determination to kick on.
"We showed that after the sending-off but the key is to do that before."
