"Oh, I can get behind explosives." He is not joking.

Computer access in general seems like an ideal priority either way. Donatello gives Layla a nod at that. A quick and easy egress is something he will never object to.

That the tunnel goes on a bit more makes him leery about another network of lasers, but this is one thing he's glad to be wrong about once they finally come across the access hatch. "Never thought I'd say this but I'll be glad to be out of the sewers."

He steps ahead to investigate the hatch. There's a simple keypad console beside it. After taking a moment to eyeball it he slips out a multitool from his beltpouch to jimmy the panel open, studying the wiring inside. "Granted alien circuitry isn't completely backwards or reversed from what I know, I should be able to trigger an override... like so."

He gives a pair of wires a quick twist to reverse their positions before he can zap himself, bracing for the possibility either way. To the side, a metallic thunk sounds from the hatch and a green light switches on by the keypad.
