"Professor Callaghan!" Hiro said, confused. The team was starting to recover and was now standing next to Hiro. "But ... the explosion. You died," Hiro said.

"No, your microbots kept me safe," Callaghan replied.

Hiro's mind was racing. "But Tadashi ... you just let him die?"

"Give me the mask, Hiro," the professor said.

"He went in there to save you!" Hiro said.

"That was his mistake!" Callaghan replied.

Wrong answer! Hiro thought, and something in him snapped. "Baymax!" he said, gritting his teeth. "Destroy!"

"My programming prevents me from injuring a human being," Baymax said.

"Not anymore," Hiro replied as he touched Baymax's chest and opened his access panel.

Baymax tried to reason with him. "Hiro, this is not what—"

But Hiro wouldn't listen. He pulled out Tadashi's nurse chip. "Do it, Baymax. Destroy him!"

"No!" Go Go shouted. "Stop!"

Baymax raised his rocket fist, and Callaghan backed away.

But just as Baymax was about to launch, Go Go plowed into him. The blow redirected the fist, which hit a cement wall. It missed Callaghan by only a few feet.

Baymax then raised his fist and pointed it at Go Go. "Get the nurse chip back into Baymax!" she yelled.

Honey grabbed the chip off the ground and tossed it to Go Go, who zoomed over to Baymax and jammed the chip into his access panel. Baymax's rocket fist powered down.

"What are you doing?" Hiro called. "He's getting away!"

Callaghan had gotten the mask containing the neural transmitter back on. He directed the microbots to grab the last piece of the portal. Moments later, he had gone through the hole in the ceiling.

Baymax blinked at the destruction around him. "My health-care protocol has been violated," he said. "I regret any distress I may have caused."

Hiro, angry and frustrated, looked at his team. "How could you do that? I had him!" he shouted.

"What you just tried to do, we never signed up for," Wasabi said.

Go Go nodded. "We said we'd catch the guy. That's it."

"I never should have let you help me," Hiro said as he climbed on Baymax's back. "Baymax, find Callaghan."

"My enhanced scanner has been damaged," Baymax replied.

Hiro groaned in frustration. "Wings," he commanded.

As Baymax's wings deployed, Fred said, "Hiro, this isn't part of the plan."

But Hiro ignored him. "Fly!" he said to Baymax, and the team watched as they flew out of the building and streaked across the sky toward San Fransokyo.

“卡拉汉教授！”小宏疑惑地说道。队员们都开始恢复了并正站在了小宏的旁边。“但是……那场爆炸。你已经死了。”小宏说道。

“不，你的微型机器人救了我，”卡拉汉答道。

小宏的大脑飞速转动着。“可是泰迪……你就眼睁睁地看着他死去了？”

“把面具给我，小宏，”教授说道。

“他冲进去是为了救你！”小宏说道。

“那是他的错！”卡拉汉答道。

错得离谱！小宏想道，啪的一声他心底的那根弦断了。他咬牙切齿地说道：“大白！灭了他！”

“我的设定程序不允许我伤害人类。”大白说道。

“现在不是了，”小宏伸手打开了大白胸部的访问端口。

大白试图和他讲道理：“小宏，你不能……”

但是小宏不听。他把泰迪的护理芯片拔了出来。“听我命令，大白去，灭了他！”

“不！”神行御姐喊道，“快停下！”

大白举起了他的火箭拳，卡拉汉向后退去。

就在大白要发射的时候，神行御姐撞向他，改变了他拳头的方向，拳头打在一面水泥墙上，离卡拉汉只有几英尺远。

大白抬起拳头对准了神行御姐。“快把护理芯片装回大白体内！”她喊道。

哈妮柠檬从地上抓起芯片扔给了神行御姐，神行御姐迅速靠近大白，把芯片塞进他的访问端口内。大白的火箭拳停了下来。

“你干什么？”小宏喊道。“他要逃走了！”

卡拉汉戴上了带有传感器的面具。他指挥着微型机器人去取最后一块传送门的部件。片刻后，他从房顶的大洞逃走了。

大白眨着眼睛看着周围被毁坏的东西。“我违反了护理协议。”他说道，“对于可能由我造成的痛苦，我很抱歉。”

愤怒受挫的小宏看着他的团队。“你们怎么能这样？我都抓住他了！”他大喊道。

“你刚刚想要做的事情，我们可从未同意过。”芥末无疆说道。

神行御姐点点头：“我们说好的是，我们一起抓住他。仅此而已。”

“我一开始就不该让你们来帮我，”小宏说着爬上了大白的背。“大白，去找卡拉汉。”

“我升级版的扫描仪遭到了损坏，”大白回答道。

小宏受挫地哼了一声。“飞行翼，”他命令道。

在大白展开翅膀时，弗雷德说道，“小宏，这可不在计划之中。”

可是小宏直接忽略了他。“起飞！”他对大白说道。伙伴们看着他们飞出建筑物，划过天空向旧金山飞去。
