Sadly for Riptide, the memories of the Sentinels are still very fresh in Logan's mind, and despite being completely exhausted, he pushes himself to his feet, his claw drawn out as he growls at the giant robot:

"So, they you talk, and that's all you can come up with?" he spats, not registering that the Transformer doesn't look anything like the Sentinels he knows. The robot is too tall, too brightly colored and not aggressive enough in trying to kill him.

It's something that nags at the back of Logan's mind, and it's the only reason why he hasn't attacked the robot yet.
